As I'm diving in code for another stuff, I see in camera properties what some cameras use 10 bits per pixel but 12 is supported except for curves (cf. "CAM_SENSOR_BITS_PER_PIXEL" property).
So, is this really supported (ie. disable curves and set bpp property to 12) in "native" by builds or is there are some changes to do in code?
Hum, why that?.. Because if you are looking for high quality, shooting in 12bpp is a huge advantage (4096 vs 1024 levels of value recorded) in dynamic and you may using RAW/DMG output, so you can use curve features in software (more accurate, using records pref', etc.).
