Are there two types of Blu Rays (YUV/RGB) and use in MacBluRay player

I was wondering if there are 2 ways to encode video on Blu Ray. Sometimes videos are YUV encoded instead of RGB. I wonder if those 2 options are used for BluRay discs as well? If so, can you tell it from some pictogram on the wrapper?
Problem is: when I use Mac Blu Ray Player, some movies look excellent, while others have really weird colours. Like NeverTheSameColor analog.... Oversaturated and clipping.

All HD content is meant to be encoded using the same color space which is known as the REC.709, however there are two different formats used when encoding blu-ray, H.264/AVC and VC-1, so maybe that makes some kind of difference, but I have disks encoded using both and I've never noticed any color difference.

Have you tried any of the movies on a stand alone Blu-Ray player to see if there is a difference?
