Only DV5 with an IPT BL and DV8.4 with an HLG BL should trigger DV playback, because those are the only profiles supported by the ATV4K.
It seems, that ATV 2021 does not use the RPU for HLG based P8.4 videos either. I checked with RESET_9999 videos.
Very interesting, so I played those files (including P5 fake/real) and I notice some periodic changes in the video stream of some of them (hue changes ?) but I couldn’t find explanation on how to interpret the usage of those test files. I did search here too, any clues/tips is greatly appreciated.
I feel really silly because I never got past the red screen in some of those files until now ... I thought the DV file was not being displayed correctly. Here's my noob observations for some of those test video files (P5/P8) using Infuse 7.3.10/ATV4K/LG E7:
1. RPU TEST SL fake p5.mp4 : dvhe.05.06, BL+RPU, BT.2020/PQ
- DV triggers, red screen, bunch of text on red/blue/red screen, scary guy staring at me
- I can't tell wether there's some scene by scene adjustment regarding to RPU
- According to recently found comment and that video display full screen, ATV 4K is not reading RPU from my created DV P5 using yusesope mode 2
2. RPU TEST SL real p5.mp4: dvhe.05.06, BL+RPU (missing meta data)
- DV triggers, some video aspects are periodically changing: brightness, hue, ... ?
- In some scenes I do notice the lights (specular highlights ?) are kinda bright.
3. RPU TEST SL p8.mp4: dvhe.08.06, BL+RPU, BT.2020/PQ
- same as (1) above
4. HLG DV P8 in sync.mp4: dvhe.08.07, BL+RPU, BT.2020/HLG
- can't tell much
