Rendering difference between integrated and discrete graphic card


on 2010 15-inch mbp, noticed when switch between integrated intel graphic card , nvidia gt 330m, color rendering different. when use default "galaxy" wallpaper, intel card top menubar appears more grayish, while when switched nvidia card, menubar looks more bluish. overall color on nvidia card seems more saturated on intel card.

else noticing this? i'm on ml gm (12a269), btw.

have made screenshots show this, identical when captured, makes sense since rendering different, not actual rgb value each pixel, think.
 

i have same mbp , can't see difference, although when installed dp3 while ago did notice looked cooler. ios 6 beta seemed cooler assumed intentional, describe doesn't sound it.

off topic you're on same system, how finding smoothness of graphics in ml, on both cards? main issue lion , hoping solved ml after upgrading gm still seems pretty choppy - hoping it's installation that's problem , improve when clean install final release.
