Mine is an LG. Ran the terminal command and verified it. Now on your idea of comparing it BEFORE running the terminal command, well I don't have a samsung sitting side-by-side to compare to. What I do know is that if I sit this display beside my MBP2010 without retina the difference is stunning and I mean STUNNING. This display is brighter, crisper and in my use through 7 hours today I have not noticed any IR. Granted I've read that it takes time to appear and it still might. But so far, right out of the box. Nothing.
I like this display so much that when I went to my doctor appointment with the older laptop I didn't enjoy working on it and that was after just a few hours on the retina.
On whether I'm right or not you raise a good point. The problem may exist. People simply may not notice it. Either way to me that results in a "happy" user. My point is simply that what you read in this 350+ page thread is the people that either have noticed or really were bothered by their displays.
I think if we went through this thread and counted up the unique number of rMBPs seen in this thread we are talking perhaps 350 pages times a maximum of say 20 posts per page that would be a maximum of 7000 unique MBPs. I would have to venture that Apple has sold quite a few more than that and I'd say my 7000 number from this thread is really high because there are lots of duplicate posters.
So my point is that the existence of this thread shows that there is a problem, at least with some rMBPs. Perhaps with all non-samsung rMBPs. The problem may be noticable only in specified conditions so that myself, grandma checking her email, or the teenybopper posting on facebook would never notice. On the other hand the problem is very real to those that depend up on the display for true graphic work which is what the Mac made its name on.
So I do not discount it. But I wanted to simply say that the "problem" even if it exists in all rMBPs is going to have different effects on different people. LIke grandma who would never even know what IR is to myself that probably won't care to the graphic designer whom it will drive them nutz.
What I don't agree with is the people calling Apple products crap for this. I do agree that Apple not coming out and acknowledging it is frustrating and probably will cost them some customers and sales. That bothers me more. If the CEO had simply said: Hey we got problems with iOS6 and maps and oh by the way, those of you suffering with the IR problem on the rMBP, never fear we got your back we are working on it! Don't you think this thread would be a ton shorter?
