I was referring to chroma upsampling: going from YCbCr 4:2:0 to YCbCr 4:2:2 or YCbCr 4:4:4. This is not expected to produce a change in luma. Yes, you are correct there will be a darkening/brightening effect for RGB Limited/Full if the display is set incorrectly.
RGB doesn't have any chroma subsampling. It can only be 4:4:4. There is no RGB 4:2:2 or RGB 4:2:0. So, in true sense RGB 4:4:4 is just redundant.
