Looking at the colour variations on the different rMBP panels i have seen, I am not sure that using someone else's calibration profile is ever going to bring you a satisfying result.
If you want to make sure to get a well calibrated screen get something like a X-Rite i1 or a ColorVision Spyder calibrator. That way the icc profile will be made for your panel and you will be able to recalibrate regularly!
Looks like its an LG. It's identical to my SJE2 default profile. (late 15") I was curious to see if there was any difference between them, perhaps there isn't. Someone posted a sunspider profile that looks quite nice, different, but I'm indifferent on whether or not it looks better.
