I got this link from Engadget. I've skimmed through it and seems pretty good comparison between the displays of the galaxy S I, II and III. There's also some comparisions between the OLED technology used in the S series compared to the iphone 4 IPS display technology. For colour accuracy I find it odd that the author doesn't mention that you can change the colour profile on the s III. You would think each colour profile would deserve a separate measurement(s).
