Today I compared the 13 and 15 retinas sort of side by side, or at least back-and-forth. The 15 was beautiful. Ever so slightly pink tinged but very subtle and not really an issue at all to my eyes. The colors were awesome. I had to know amidst this whole LG-Samsung debacle I read on these boards which display I was staring at. Coincidentally, or maybe not as I'm not a retina owner and have no clue, it was a Samsung screen as told by the Terminal code prompt. The 13 I tried running the same Terminal prompt but it didn't spit out any details. Anyways, the 13 seemed like OVERLY OVERLY blasted with pink tinge and seemed to be coming on stronger from the left side. The colors didn't jump out of the screen nearly as much, either. Reminds me of the iPad 3 endless swap game I did to find an evenly tinted display so I could iron it out in Color Profiles jailbreak tweak. When there's hot pink bleed shooting out of a corner of the screen, or some other odd and obvious uniformity issue, they weren't something I could look past. Anyways, has this been your experience as well? I'm sure like anything Apple, depends which manufacturer made your display and luck of the draw with the wild card stock calibration/QC variance.
