Using photoshop I altered the kunark loadscreen to match what I'm seeing since this patch went in. I tried doing this with my cellphone but the images are so crappy looking I feel it would just confuse the issue more.
First image is the un-altered Kunark loading screen. If your system gamma is currently normal, it should look normal. Second image is an extremely close approximation of what I now see as my loading screen. I'm running winXP with a Geforce 8600 GT, latest drivers.
