@TimSportsschuetz: You normally cannot determine the manufacturer of individual components on most notebooks made, the fact someone figired out how to do it on the 15" is great but not usual or normal. As for your submitting the issue to forums and tech sites, good luck. From just reading the last few pages from you newer people it's clear that not many have read through this thread and none of you have stated any actual FACTS about this issue, it has been almost 100% speculation. I doubt any reputable site would write about this issue based on a forum with no hard facts available, but it may get some of them to pursue finding out whats really going on. Also if you read a bit more of the thread you'd know that all versions of rMBP 15's have had both screens with no decipherable pattern. As to the 478 pages, there was actually a reset after the first 500 pages or so. But even from say 1000 pages you have to look at the actual number of people who reported having IR on their machines. A vast majority of the posts here are from people complaining about the possibility of getting an LG with IR or about how to win the 'lotto' by returning an LG screen, without even testing for IR, in hopes of a Samsung. Cosidering Apple produces approx. 133,000 rMBP per month and taking an educated guess that there have been less than 1000 people on this forum who actually have reported significant IR, the failure rate is fairly low. Even if you conservatively figure the 1000 people with IR on this forum are just 1% of the total overall that is still less than a 10% 'failure' rate. Is that good? No but it's not nearly as bad as some make it out to be. Keep in mind Samsung has had several documented issues also: Yellow tinted areas, dead pixels, lower contrast, lower color gamut and the inability to calibrate accurate an white point.
@Bolomk33: The 13" only has a dual core CPU and the intel integrated graphics, there is no discrete GPU. All the reviews I've read for both sizes have been very positive about the great heat management system Apple has designed into the rMBP's. I run my quad i7 2.7Ghz CPU at 100% load (on all 8 threads) for hours at a time daily doing huge batch processing files (10 to 50GB) in photoshop. Heat is definatelynot an issue on the 15".
FYI, Anyone can add Applecare anytime during the first year standard warranty period to get the additional 2 years coverage. B&H photo offers Applecare for the 15" for $244 USD ( I believe in the USA only) which saves $105 over Apple direct pricing.
For the record I have a flawless LG 15" display as do 5 other local photographers, 2 of these were from the initial pre-order release date and all of the machines are our originally received units. One local has a Samsung and returned it due to inability to calibrate an accurate whitepoint, he just received his replacement (Samsung) and the new display has several dead pixels. He says Apple has been very easy to deal with and even offered to send his new replacement in advance of returning the one he has (due to the downtime and hassle) but it goes to show you Samsung is not perfect either.
