I can upload the calibrated profile for my LG screen if anyone cares (each screen being different etc.). I used a Spyder 3 to do it and chose a white point of 6500k, with some ambient lighting present.
One thing that surprised me that the preinstalled profile was already very close to the calibrated one! The calibrated one is just a touch warmer. For my old MBP, the cal. profile was vastly different from the preset!
The more the merrier... subjectively mine looked close to the default after I did the Display preferences eyeball calibration ..I didn't need to adjust very much using that .. The other thing I realized is that, because we have 2 graphics adapters in play in the Retina ( Intel HD and nVidia ..) , I should have specified which adapter was active (or switch to use only 1) .. they could produce slightly different results .. I'll be profiling again in 3 weeks after the display is 'seasoned' ..will post that one and specify which adapter ..
