So, VDPAU studio color conversion should be disabled. What about RGB vs YCbCr444? Does that have any bearing on the picture quality (of the video stream, not the GUI)? Am I correct in assuming that RGB would be better, since apparently it gets converted to RGB full whatever you do, so another conversion step by the video driver from RGB to YCbCr444 (or RGB limited for that matter) is not helpful?

Second question, is there any reason why everything HAS to be converted to RGB (full)? Wouldn't it be better if the video stream was just outputted natively to the screen and eliminate the conversion to RGB completely? Isn't that what dedicated BluRay players do, too?

Bring your eyes close enough to your display and you may see RGB in action. So that's a given, we render to a RGB buffer provided by the graphics card which represents the monitor.
The ideal solution may be:
- get a monitor (TV) which supports full RGB
- switch off all image processing done by the TV between the input and the native panel
- calibrate the monitor -> get a color profile
- use this color profile in XBMC
