yep, just sell that TV and get an LG lol.
Even Dolby recommends to the colorist the LG C7 or newer for previewing.
Not an option. I like Sony's motion handling and HDR10 8)
New 2021 Bravias will support TV-led DV

you got me curious. I checked that scene on my x700 and I find FEL DV sightly cleaner than HDR10 and P8 DV.
thank's @lexyz for the samples

HDR10 vs P7 FEL: https://screenshotcomparison.com/comparison/10301

a lot more obvious with the capture card.. wow:

I'm not regretting my CX OLED, it's fantastic, as a display I love it. It's so good.

I'm not gonna end up worrying if I ever put a DV movie through Plex and it looks bad for some reason. There's always the HDR playback...

but unless @Manixx2020beyound gave me the wrong capture sample, it looks that the p8 single layer file also fixes the artifacts.. WTF??? now I'm confused...

Possibly better processing, dithering by the Dolby Vision engine regardless of EL.

we found out what happened, he misnamed the capture of the p4 dual layer sample from lexy to p8. sorry

here's the real P8 SL vs HDR10 source: https://screenshotcomparison.com/comparison/10306
so the artifacts are there, appears different because of the brightness difference probably caused by the dynamic metadata.

So yes the FEL can make a HUGE difference.

But does it work on the Shield after all?

nop, i confirmed yesterday that the shield is ignoring the EL. Well Nvidia staff also said it a while ago as Shawn said.

Total Recall is extreme example.
EL is about 40% of bitrate in this scene. Very rare case
Demo-level stuff 8)
Jokes aside it's a defect and it's a mistery how such grade passed quality control.

Seems like all film grain remains in FEL :)
Do you understand now why StudioCanal disks called "blocky-vision" on blu-ray.com? :lol:

Just wondering how much more off an impact is the fel in rgb dv 8bit doblyvision.
I think the super red color change has something to do with the bt2020 vs p3 encoding.

Greetings to you all. I would like to ask what it looks like now playing with Dolby Vision movies in mkv in Zidoo z9x. Does FEL and MEL play it? I have a Shield for 2019 and I'm considering buying a Zidoo z9x if it pays off. SHIELD plays just fine FEL and MEL. I read that the Zidoo z9x has better colors. Thank you for your help.

So, you guys saying that DV on MKV on Plex/Shield is faulty.. will it ever be fixed in a possible update no matter how long it takes, or are we doomed?

As far as I know, FEL titles will never be played to their full capacity on the Shield, because it's simply a hardware limitation. MEL titles on the other hand and the color issues that exist with them, nvidia is still working on it, but since DV rips from disks are not really officially supported, only time will tell if and when that gets sorted out.

I do have a Sony UHD BD player that has Dolby Vision, particularly the 700 something, but with the new TV I legit do not have the space for it, so I can not hook it up in any form.

But even if it was possible, I do prefer the much easier, faster, click and play part of streaming instead of putting disc (remember in the Sony Blu rays, you have to manually switch on and off DV everytime you play a DV disc!)..

My TV can play MP4, TS, M2TS DolbyVision files via Default player and MKV DolbyVision remuxes via Modified Kodi (32-bit version)\
Any idea which format is best for accurate color and quality?
