1. YCbCr – 4:4:4 pixel Format
2. YCbCr -- 4:2:2 pixel Format
3. RGB – 4:4:4 pixel Format Studio (Limited RGB)
4. RGB -- 4:4:4 pixel Format PC Standard (Full RGB)
Chroma upsampling is not expected to produce any change in luma. I haven't noticed it on X6, but I will specifically check for it. You can also check the quality of chroma upsampling using the chroma burst and error patterns in Spears & Munsil HD Benchmark disc.
BTW, there is no luma/chroma components or sub-sampling in RGB color space.
