YCbCr has two color standards: 601 for SD and 709 for HD. We've found that A/V gear manufacturers are sometimes confused about what standard to use. Oppo does it correctly, but not everyone else does. RGB has only one color standard, so it is safer in that respect.
If the display behaves properly then there is nothing wrong with using YCbCr.
I believe the signal is converted to RGB in the display anyway.
