Dolby Vision now possible through MP4 Mux.

Haven't check mkv yet, but with old p4 ts I can clearly see red tint in "horses", "deer" and "stopwatch" scenes.
Bravia (player-led DV) + Shield TV (Plex 8.4.0.19231)
AVR reports input signal as BT.2020 12bits Dolby Vision

Same with mkv and Exoplayer (23/07/2020)

Oh I had no idea the x700 supported single track dual layer files.

The saving private ryan flickering issue is also another big concern to me. too bad it's FEL, I can't test the single layer el+rpu on the x700. But I don't recall that I noticed flickering when I watched the dual layer TS.

I have it in dual layer TS on my x700 and there is no flickering.

[RESET_9999]

So, I did more comparison with my x700 and I just can't get a perfect match with any of the single-layer BL+EL+RPU( FEL or MEL). I'm starting to think that the Shield just can't play them properly because I can get a perfect match with the genuine profile 5 full range files from streaming services but never with the uhd-bd rip. It actually makes sense, maybe the shield was never meant to play dual layer rip.

Using a real profile 5(BL+RPU) test pattern, the Vertex completely fixes the red push issue and the colors match the x700 perfectly.

Could definitely be the case that the Shield just wasn’t meant to play back these kind of files. There is confirmed support for profile 4 MEL, though, so I’m wondering what kind of media they had in mind for the implementation. The only official profile 4 video I can think of is the lg demo from here: https://4kmedia.org/lg-dolby-vision-uhd-4k-demo/. I haven’t looked at this video closely or compared the playback off anything else to see if there’re any evidence of the red push here.

That's really bizarre. That's completely different than the results I saw. I'm not able to take screen shots to show it, but, the picture was identical on the SM benchmark demo between my UB820 and the Shield. And I was not using the Integral 2 to correct anything at that time. And yes, I do get the red push problem in other videos. That Doctor Sleep sample that shawnc22 posted, as an example, I compared with my LG internal player vs the Shield and definitely saw the problem. So I have no idea what the pattern is here.

The difference can be hard to see but if you compare a scene with a lot of red colors, it's more obvious.

I've conduct the same comparison with your pattern DV file.
I compared the mp4 played with my Shield RGB bt2020 and with in-app Philips
Shield Normal VS Philips TV https://screenshotcomparison.com/comparison/4946

And my results seems slightly differents
Cyan is brighter with my shield but i'm not sure about a red push
it's very strange

interesting..... yours appear undersaturated compared to the philips and yes indeed, very different than my comparisons but I noticed your taking pictures in a bright room. My pictures were taken in a complete dark room ( black velvet everywhere) without any light. Perhaps thats the difference ? I dont know but I'm clearly getting the same color difference no matter how many comparisons i do.
Also, I assume your camera settings are locked?

EDIT:, you sure the signal is RGB ? I don't know what DV type the Philips tv supports, maybe LLDV ? that would explain why the red color seems ok.

It's not in a bright room, just ambilight activated. I could try to turn off ambilight.
And yes I locked my camera Settings (ISO, Shutter Speed, Aperture, White Balance)
I will also try later today or tomorrow the video with plex running on Philips to see if the problem come from Multimedia App or Shield TV

I can't tell there is any noticeable red push
Bravia internal Plex vs Shield Plex
Bravia's internal apps are brighter, so ignore brightness difference

do you have any device that can tell you if you are getting RGB 8bit DV or LLDV 12bit?

yeah, with a Sony TV, you shouldn't have any red push with genuine profile 5 files or from any streaming apps.
but thats a huge brightness difference!!

My TV tells me that I receive 8bit RGB when using Nvidia Shield
