You should make a review video. More prospective customers should be aware of these flaws.

Yep, I will for sure and I’ve collected all the data I needed.
I emailed my retailer, and they contacted KS and told me to wait for their response before returning it.

It would only be logical they go bankrupt soon.

It's clear they "added" HDR and DV as a marketing ploy to get more people to buy it. The concept is marginally good in theory. "Own" movies before they're even released to streaming to buy much less on physical disc. And the promise of quality that rivals or surpasses disc. And I think for projector owners using SDR that's probably true especially if you combine that with a lumagen or envy. But the expense involved, lack of true ownership of your media, and quality issues of media doesn't really make it a viable platform for anyone except people with money to blow. And if you have money to blow, I'd argue you're better off with a giant NAS and physical media. Add an Ugoos to the mix and you're good to go. At least with that setup you have true ownership of the media.

Plus Movies Anywhere platform might even have better quality, and the app is available on a 50$ streaming stick lol... Imagine paying 97k $ for a streaming device that has subpar encodes :lol: ...

You will love it :)

Yes, CPM build is a must for the true tv-led option: ''source metadata''. DS workflow 3-2 will be identical to CPM HDR10+ conversion as long as you use the histogram plus.
ps check your pm, I've sent you a link to my GD RPU collection. all you need to do is inject with workflow 1.
Amazing, will definitely give the injection procedure a shot.

Can you verify I set the right settings for my use case in CPM System -> CoreELEC -> Dolby Vision?
Mode: On demand
Type: Display Led (DV-Std)
Dolvy VSVDB: Off
Colimetry: disable/remode
Source levels metadata: On
Level 5 & 6: Source
Restrict overlays: off
Preferred HDR for dual Dolby Vision and HDR10+ content: Dolby Vision
Dynamic HDR10+ to Dolby Vision profile 8.1 conversion: on
Prefer conversion over original Dolby vision: Off
Peak Brightness Source: histogram-plus
For SDR8/10: Off
For HDR10: Dolby Vision
For HLG HDR: Dolby Vision
For Dolby Vision: Off
Convert profile 7: Off
This has been running great on my setup (E6 connected through an Onkyo RZ820 AVR). But I have run into a strange problem with a few titles (O'Dessa and The Legend of Ochi webrips):

When I start playback of O'Dessa, the TV displays the DV logo, and then just goes black and displays a black screen. Not even the Kodi OSD or the volume OSD from my AVR. Audio is playing, and I can stop the video via Kore or if I hit the stop button while "blind". "The Legend of Ochi" starts to play fine, but at around 12 minutes, the screen goes black, and in this case, the picture comes back at around 22 minutes (I can skip forward to this point to get the picture back).

If I disable "Source level metadata" both files play fine. I guess there is some metadata "too complicated for the E6" that makes this happen?

I can live with turning off SLM in these (few so far) cases, should I run into other problematic media, but of course, I wonder if there is a fix, or something that can be adjusted?

Strange, but sounds like a source issue. Do you have a sample we can try? I never had a rip that wouldn't play on mine.

I would have written it off as a single source issue too, if it hadn't happened twice in a short time (if it is the same issue with both movies that is). I sent you a PM.

It may not be all the Kscape titles that have color issues. I just tried another one(Poor Things) and while there is some slight difference on some frames, nothing as bad as Mad Max, Last of Us and Accoutant:

ps: This is a massive comparison: 1080pBD vs KALEIDESCAPE vs Movies Anywhere vs Disney+ vs Amazon vs iTunes. 36 frames, pics are in HDR and can be viewed in HDR on Chrome/Edge.

Are you all mainly looking for the ease of access to the titles? Using these planned obsolescence devices is not a wise decision, but I understand if the concern is mainly the ease of access to the titles, not the device or file properties.

I feel like someone needs to keep reiterating to newer people that if you don't need Dolby Vision Profile 7 at UHD bitrates, you can use basically any streaming device. Since most people are fine with Profile 8 at half UHD bitrates (~50GB files), a used ~20usd Amazon 4K Firestick will work fine with Kodi or NOVA Video Player (but you do need a WiFi 5+ router).

Well first night with the Kscape was not very good... Tried two streams: The Accountant and Last of Us S02.

Accountant:
horrible Raised black in both HDR10/DV
DV to HDR10 conversion is incorrect
1080p SDR stream different master/framing and actually better than 4K!
https://slow.pics/c/YShhgXTe

Last of us:
Doesnt look right at all, brighter than MAX webdl...
https://slow.pics/c/U1B6JARQ

the only format that seems right is SDR:
https://slow.pics/c/pZkJmdrO


OK, tested a new movie on KSCAPE, and it's the same crap. Blacks are not raised like in The Accountant, but the colors are desaturated and the brightness is not right. DV TV-LED is even worse. Compression is also slightly worse despite the much higher bitrate on KSCAPE. Definitely a terrible streaming service or device, at least for HDR10/DV, because SDR is fine.

MAD MAX DSLR Camera settings locked:
KS DV vs KS HDR10 vs Ugoos HDR10 vs G5 internal player HDR10 vs Ugoos DV

lossless HDMI capture: https://slow.pics/c/ZNkOXm8g
heatmap: https://slow.pics/c/1Gx2U3Xp?canvas-mode=fit-width

Last of Us S02E01
And I've measured the whole Last of Us S02E01 episode. The KS stream(DV and HDR10) is 3 times brighter:
madvr plot(KS HDR10 vs MAX HDR10 vs MAX DV): https://slow.pics/c/OrY8Z2dl
DSLR camera (KS HDR10 vs MAX HDR10): https://slow.pics/c/pZEYwEHS
25 lossless HDMI capture: https://slow.pics/c/Z5uGaBPM
KScape HDR10 metadata are identical to the MAX web-dl:

MAX WEBDL:

The Accountant raised black

G5 KS HDR10 vs UHD-BD HDR10: https://slow.pics/c/23KldS02
Hisense TV KS HDR10 vs UHD-BD HDR10: https://slow.pics/c/nFzaM7c5

The only format that seems right is SDR:

EDIT: It may not be all the titles that are affected. I tested a few more and these were ok:

https://slow.pics/c/skNSEG29
Very interesting, thank you for this.

This also explains why I thought TLoU was so darn dark, Andor, too. It's not me or my TV, then. It's the silly dark HDR (C2, P5, internal player).

If you're talking about the Kscape I think the idea is to get access to content at the highest quality possible. Unfortunately it seems that device/service does not live up to the marketing hype.
