Hey guys, So I got my rMBP (2.6/8/512) from Amazon and was floor at how amazing the screen truly is. The colors are so much more vivid and the contrast is so much better than my matte 17" MBP and even my 27" ACD. I ran the serial number check and it shows week 44 production with only 1 cycle on the battery. So I did the terminal command the discovered I got the LG display. Yes, the blacks are deep and inky. The lower brightness didn't bother me all that much since I never really use it in brightly lit outdoor spaces. But the problem I noticed immediately is that the right third or so of the screen has a very slightly warmer tint. It's noticeable when it displays whites and grays, like when I view a web page in Safari. As a little background, I am a photography enthusiast and plan on using Lightroom to do color correction. I calibrate all my screens with my Spyder4. But a slight warmer tint on one side of the screen cannot be corrected as the profiles affect the whole screen. I took the time to visit my local Apple Store and found that all 6 of 6 rMBPs on display were LGs and ALL had this slight tint on the right. I can quickly spot it now since I know what to look for. I've only found one Samsung display at the local Bestbuy and it seemed to not have this issue but it was showing the well documented "bright spots" which took me by surprise. Even more of a surprise, I looked up Anandtech's review of the 15" rMBP and noted that he too had this slight tint on his review unit based on one of the screenshots he posted with Safari running. So is this the current state of the rMBP displays? I tested for IR and have not noticed any issues using the checker pattern app. And the computer simply screams. The scrolling is fine except when I am on FB or The Verge. My dilemma is that I don't know whether I should take the unit to Apple and hope that the Genius sees what I see and swap out a unit for me, even though I didn't buy it from them directly. I can't swap with Amazon as they are currently out of stock and I am one of those who got really lucky on saving $400 on the computer recently. If I get another LG, it may be the same or worse with deal pixels and IR. And the odds of getting a Samsung are getting lower and lower as the sample units in the Apple Stores are 100% LG at the one store I went to. So what do you think guys? Thanks for the advice!
