Dolby Vision now possible through MP4 Mux.

yep, that's how the eagle beak is supposed to look when Chroma Weight is working and this is exactly the bug described in Vincent video.
L2 CW is rarely used by colorists though.

Seems that the out of sync issues I get with DTS tracks in Kodi is only when Dolby Vision is used, HDR only and 1080p titles with DTS sound play fine, without sync issues. Installed the Plex mod also and manifests the same. Only option I got now is to try to get DTS coded enabled after rooting as I suspect there is some DTS transcoding done by Kodi for DTS, as the TV cannot decode it.

This is so twisted for us mere mortals, do we conclude that on my LG E7 & Oppo set to "TV led", that indeed it is TV led bcoz the eagle's beak with "no chroma weight" is meant to look as in my photo. Gotta now find that video from Vincent, oh this one: TV led vs player led

yeah, I gave up on lossless audio. I'm still happy with DV MKV + EC3 audio, it's as stable as Plex(TS) plus SRT/SUP subs seem to work well. Resuming movies/shows work too as far as I can tell.
The audio selection using the Plex addon seems inverted though. My movies all have lossless audio + EC3 and if I want the EC3 to be selected by Kodi, I need to have Plex configured to play the lossless track.

Yes, the LLDV bug described in that Vincent video is the L2 Chroma Weight not working on cmv2.9 devices. Turn on player-led on your oppo and CW will no longer work.

You have to sideload Kodi in developer mode but it's not too complicated to do and its pretty nice to finally have DV MKV support on LG TVs.

Would this be able to play MKVs on my C9 that are Profile 7 FEL?

I see the discussions currently that lossless audio might not mix with TrueHD... if so, I'll pass on this setup because I have way too much lossless audio in my library. At that point, I may as well just convert to m2ts for special viewings and watch from my Oppo, right?

ok, I'm starting to understand what's going on with the different RPU responses on players in TV-LED and in LLDV. It seems the x700/x800m2 almost completely ignores L1 and always tone map to the TV edid target.

Yes, oppo and all bluray UHD players change the PRU in TV-LED mode. they change the data from the RPU and then it goes to the TV.
Shield tv does not touch the PRU.
I will show in a video soon how it looks like in the video data from the RPU.

It would be nice to decode back from the binary code of the RPU video to see what changes there specifically. But I don't know how to do that

if I understand what you’re asking, you can use dovi tool to convert (export or info) RPU.bin or specific frames to json, lots of ‘low level ‘DV RPU info in there.

No, I physically see the RPU binary code in the ycbcr data video stream.
here's my video of what I'm talking about and how it looks from the TV and player's point of view.

Ah you want to capture then view the extracted RPU from the DV bitstream sent from a player. In that interesting video (hard to follow as its subtitles were TTS), he somehow captured the video stream via a capture card & is viewing it using DaVinci ? Since it's TV-led, I think the TV-Led video signal (DV) is tunnelled over HDMI via RGB 8-bit so I am guessing any 4K video capture card can do the job but I am unsure.

Odd, your username is the same as that YT video's channel ... Oh darn, are you the author of that YT channel & that video you shared above ?

The conclusion in that video summarizes what you're asking about, sorry way above my pay grade but very interesting video, thanks for sharing

Yes, I guess the ST P7 MKV would work on the C9 kodi app. Let us know if you try.

Yes, I am the author.
I will try to make a translation for this video in English, I agree that it is hard to read subtitles and try to understand what is happening on the screen. auto speech translation misinterprets words, changes the meaning a lot.

And about decoding RPU from the video, I think it is possible if there is no encryption. But it's complicated.

does this mean bluray UHD players should also be categorized as 'fake TV-led'?

Is the EDID info shown using the TV itself or some other method (Pgenerator on rpi mentioned by RESET) ?

No, the TV still does the processing, but UHD players give it some hints based on EDID data from the TV itself.
