Ah Yes fritsch, I should have taken more notice of the Kodi Log....

NOTICE: GL: Using BYPASS render method

So we can get 10-bit output out of AML S9xx devices so long as the Kernel the 10-bit video output.

Yeah :-) it needs an intelligent kernel to render 8 bit stuff correctly though. Ever thought what should happen of "standard" 8 bit content when output on a 10 bit display?

Yep... I guess if you aren't careful the 8 bits are ranged from the LSB not from the MSB... (So you get a very dim picture...)
