I have a late-2007 Macbook Pro (MacBookPro3,2). I've noticed that over time, the colors on the internal LCD "drift" -- sometimes towards extremely high-gamma, oversaturated, with a blue tint, and sometimes towards dim, desaturated, grey.
If I open Display Prefpane in System Preferences and select the "color" tab, the colors snap back to their "correct" values after a several-second delay. I don't need to manipulate any settings, just open the color tab in the prefpane. I have always left color management set to the "Color LCD" preset. In all cases, my external displays (I use a Dell 2407WFP at home and a Dell 1907 at work) are unaffected.
The system is running Snow Leopard (10.6.1), and I have also experienced the problem under various versions of Leopard. I never isolated if there were any versions of Leopard more or less likely to experience the problem, although it has happened once or twice each month I've owned the machine.
I have had the logic board replaced under warranty for the nVidia 8600M failure problem, and this problem occurred both before and after that replacement.
This isn't a deal-breaker for me, but it is annoying, and leads to the occasional "wait, what?" moment when things on the display look subtly "not right." Any idea how to fix this?
