just to pick up one of the posts earlier:
LG is not automatically bad ... it is even the opposite:
Having an LG rev. 2 panel (at least on the early 2013 15 rMBP) is even the better choice than the samsung panel
I couldn't agree more. My 15-inch early-2013 had an LG-rev 2 on it and it was stunning. So stunning actually that when I brought home my 15-inch late-2013, I couldn't even look at the Samsung display.
I had to exchange it 3 times to be able to get an LG display instead.
The first Samsung panel was yellow at the bottom. You could almost see a straight line running across - with my mail app open, messages on the lower half of screen nearly looked greyed out. It was *that* bad.
The Samsung panel on the second machine was even worse. The whole screen was yellow from top to bottom, and the right side nearly beige. Almost looked like the backlighting was dimmed on one third of the display.
The third one, finally an LG. Perfect white point. Perfect gamma. Amazing color saturation. Whites look like snow and blacks are incredibly deep. Ran the IR test for 20 minutes on full brightness after making sure to run the machine for a while. Nothing wrong here either.
I personally don't agree with people saying that a uniform yellow screen is acceptable and can be fixed through calibration. Calibrating reduces brightness significantly on an IPS panel. I'd take the uniform yellow over the uneven yellow spots any day of the week though but this wouldn't be really true to what my eyes see as 'white'. Especially next to my TB display that's a tad on the cold side.
In the end, when you're lucky enough to get a good LG panel, you get a much more accurate screen. Good Samsung panels with no yellow spots and no darker areas due to uneven backlighting always look off to me. They don't look as crisp and I can really tell from the naked eye which one is which I could almost skip the terminal command.
Should I be worried about my LG-IPS ghosting in the future? Maybe. Unfortunately, the same applies to everything under the hood. Should I be worried about my dGPU, SSD, logic board? Potentially.
Heck, my 2008 iMac showed some signs of IR after a couple years. If ever the problem arises in a year or 2, I'll take care of it with AppleCare or my American Express extended warranty. I don't want to make myself sick over an issue that I *might* experience at some point in the distant future. Most likely by then, I'll have another rMBP, IGZO technology will be further improved and available within the lineup. (Which by the way, like a member mentioned in another thread, isn't free from defects either. Google 'yellow tint iPad Air' and have a blast.)
I also think that people need to realize that by taking a magnifying glass up to their screens, they will find the dead pixel they can't see or the darker spot that's normally unnoticed. As long as my naked eye can't see, I'm fine with that. I was bothered by the yellowing, it took a couple tries but I found the 'perfect' one that satisfies my eyes at a normal distance of operation. Now that I have, I'd rather enjoy my awesome machine and worry about something else in the meantime.
And there's also that 1% of my being that feels really great about using LG vs. Samsung.
