Then I went back to XMB and downloaded an RGB picture with BTB and WTW bars. When setting RGB to limited the BTB and WTW bars still merged correctly just like the blu-ray callibration. And when increasing brightness I could clearly distinguish the separate BTB and WTW bars, proving that even in limited RGB setting ALL GRAYSCALES were displayed!
When setting RGB to full, I got crushed blacks. Increasing brightness would resolve this, but that would mean that when watching movies this would now result in a too bright picture.
So grayscale in RGB LIMITED is comparable to grayscale in YCbCr, grayscale in RGB FULL is darker than that in YCbCr.
I agree... partially.
First make sure your TV is also set to FULL RGB (aka HDMI Black Level / Expanded Black level, depending on the brand), then go back and redo the tests. You should get nearly the same results.
The HDMI (Expanded) Black Level on your TV has no effect when playing video content (BD) as long as you don't force video playback to RGB (see other posts). When you play video content the TV black level is automatically set to low/limited, regardless its previous setting, but when you return to the XMB your TV changes back to the RGB domain and that's why the HDMI black level must be set according to the PS3 RGB setting.
PS3 RGB = Limited -> TV black level = low/limited
PS3 RGB = Full -> TV black level = normal/full
If you mix the settings you still get optimum calibration for video content (since RGB DOES NOT AFFECT YCC), but you'll end up with crushed blacks when playing RGB content (games, XMB).
