Functional Status of Color Management schemes with NUC7i3BNK using embedded PMP 1.2.3.623

"Legend for Video Color Processing Chain"
Player | GPU | Display
(mpv.conf: video-output-levels) | GPU(autostart.sh: xrandr --set "Broadcast RGB") | Display
  • Limited | Passthrough | Limited - Photos and UI colors are displayed correctly; Videos colors are washed out due to additional clamping at the GPU. This is not an issue with previous NUC models. Something is broken here making it function just as if it were Limited | Limited | Limited–which is an incorrect color management scheme
  • Limited | Full | Limited - Photos and UI colors are displayed with crushed blacks; Video colors are displayed correctly
  • Full | Full | Full - Photos and UI colors are displayed correctly; Video colors displayed correctly but is single scaled with BtB and WtW signals clipped
  • Full | Limited | Limited - Photos and UI colors are displayed correctly; Video colors are displayed correctly but is double scaled with BtB and WtW signals clipped

Kodi is aware of this issue and have patches to resolve this issue with these new Apollo Lake and Kaby Lake NUCs. Not being a sw developer, I am not sure where they are doing this.

This applies to the NUC6i7KYK Skull Canyon as well. Common denominator is DisplayPort.
