@wesk05 - damn, thanks for running the tests. It's nice to see numbers behind my eyes making me think I was going crazy.

There is a difference between the native Photos & Videos app and other video players. 8/10-bit output is OK with Photos & Videos, but 12-bit isn't. Only 8-bit output is accurate for Kodi. I have no idea why there is this difference between the native video player and the other video players (Kodi, SPMC, MrMC, Vimu, Archos etc.) All use MediaCodec (Surface) rendering. The tables below only show the values for primary & secondary colors. I have checked 21-point grayscale and classic color checker patterns (8 & 10-bit) and they all show similar errors.
Values that deviate from reference by more than 10 are in red. Up Sampled is 8-bit pattern to 12-bit YCbCr 4:2:2 (table 2) and 10-bit pattern to 12-bit YCbCr 4:2:2 (table 4).

Only 8-bit output is accurate for Kodi.@wesk05, so is the 10bit output from HDR Netflix and HDR Amazon Apps accurate (enough) as well vs Kodi ?
