1) Some avr's have an issue with RGB input, even though they should pass the signal
2) Even though displays process RGB internally, some cannot accept RGB as is, they convert it back to ycbcr upon receipt, then back to rgb for processing.
3) Calibration differences can be different. Meaning, if my display was professionally calibrated by someone like Chad B for ycbcr 444, the calibration loses accuracy when I give it RGB. Brightness settings can also be off, depending on the display.
4) Some displays dont function well with the auto color space mode, so you have to manually go in and change the setting when you have an RGB input.
Most set top boxes send out ycbcr 444, and generally thats what you want to use on a blu-ray player, for all of the above issues. RGB is fine for video games, there is no calibration standard there.
For streaming, blu-ray, DVD, something like and RGB output can cause issues in the video chain that would not be there with ycbcr. All the time? no.
For one example, my VT50 has a pure direct setting where if you send it RGB or ycbcr 444, processes it untouched. Problem is, that setting works great with ycbcr 444, but not RGB 444. So now I have to turn that setting off for the xbox and blu-ray, which in turn I have actually degraded image quality slightly (VT50 performs better on chroma tests with pure direct on).
Finally, the PS3, and all other blu-ray players out there generally offer simple color space adjustments, as well as bitstreaming audio. These arent deal breakers, Ill be keeping the Xbone, but M$ has a little to learn about being the all in one HT device.
So, I disagree with you using one sentence to dismiss RGB vs ycbcr color space. It depends on the display, and other devices in the chain. There is one fact though, just about all devices function fine with ycbcr input, but not true with RGB input. There are numerous documented cases with Roku's not playing well with an AVR, or a display. They all output RGB, which is a ongoing poor decision on their part.
