Yes with JPEG2000 out is always XYZ,
Only the precision change from 1 to 38 bit depth.... And can be 
different between each component, and signed or unsigned values .....
For dcinema its fixed 12 bits for all components, with unsigned values.
Maybe we need to implement an interface with libav to retrieve all those
