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!
