I thought it was odd as well. Using Avia I can get the saturation panels pefect but not the hue boxes. The only options I have are the 5 preset settings, cool2,cool1,normal, warm1, warm2. I've tried all 5 and playing with the color but can't get hue and saturation to be perfect.

The my color settings are pretty much useless. When you access that mode it throws a default test image on the screen. You can't adjust these with any source imput.
