Well, theoretically, you have one channel each of red, blue, green, and luminance (they use a green channel for luminance because it most closely matches the human eye). So yes you get more accurate color information, but also more dynamic range. In the real world you never seem to get that theoretical gain, but I would expect about 2 stops improvement (rather than the 4 stops theoretical).
