I guess you should be referring to a defective Samsung display, since mine is nothing like that. I changed my non IR SJA1 rMBP for my current one to avoid potential future IR issues, but would say that other than being a little yellowish originally (already corrected through calibration) it does nit have anything to envy from the LG.
I'd love to see a bunch of rMBPs side-by-side so we can see the differences in everyone's displays. I think they're all over the map, honestly.
