Whenever Portal launches, it sets the color settings to the OS X default, godawful blue tint stuff instead of using the values from the color profile. So to get it back to the calibrated values, you have to pull up the display settings to get it to reapply the profile. Blizzard ran into this a while back in WoW when they put their GLL rendering engine in. It wasn't actually changing the profile, it was just whatever it was putting in the GLUT table.
