I don't think so... previous releases didn't have the same problem. since beta 2, i used to place exactly the same wallpaper under mac OS and under guest OS windows XP, and i hadn't noticed any variation of gamma or luminosity when i was switching from an OS to the other.
in RC1, my wallpaper is really slightly too dark, compared to the same in mac OS. of course, all apps are affected.
And, the big problem is that you CAN NOT set the gamma (for example with "adobe gamma" control panel) in guest OS, probably because the video card in windows, in this case, is not a true one, but is emulated.
I think it could be very usefull to add a feature in paralells desktop preferences to allow the user to set a particular gamma or ICC profile in guest OS.
