sRGB IEC61966-2.1 is the most accurate colour profile for the mbp. I toyed with user settings on here and even tried my own but nothing compared to it. It exists on all of your MBP's along with ProPhoto RGB which is also very good but contains slightly too many blacks for my liking and also causes some issues for me when using .raw files.
So yeah, sRGB IEC61966-2.1 - dig it out and smile at your beautiful display
