@Danny - it may be worth getting it repaired. My Samsung display does not suffer the yellow problem, so it's not an "every Samsung" problem. You could make a note of the terminal command and go to an Apple store and try it on a few RMBP's to see if any of them have the Samsung, and then see where the color is to get a first person view.
@gam3r - I brought my laptop into the store so they could verify the problem, and less than 24 hours later they called that the part was in, and that I could drop off my laptop. From when I dropped off my laptop (Thursday after work) it was only about 28 hours before they called that I could pick it up again (Friday after work). Certainly in this case it didn't take a week. They *should* have some rough idea of how much work is piled up and how long it will take. If they're saying it's going to take a week, do they have that much traffic at this store? Or is it because they're gong to ship it off for a repair rather than do it themselves?
For all - they were very careful noting anything on my system (pristine was how they described it because there isn't a single scuff on mine). I was actually surprised when I picked it up, because it was wrapped up in a protective foam sleeve. Compared to the idiots in my home town here (Racine Wi) that looked like a kid in his basement, laptops just laying loose, my store at least careful with the finishes. I had not a single mark I could find indicating anyone other than I had touched this in the first place. YMMV, but at least there's hope that this is a standard procedure for their repair people.
With my previous 2011 15" i7 I had the bottom off a LOT. Changed around drives quite a bit finding one I liked, memory, etc. In the first month and a half I must have had the bottom off at least 40 times. I never had any marks or weakening. Granted, any person could strip something out, but I'd think that people having issues like that would be in the minority, since even in my case, having done it that many times, I knew just how to torque the screws simply from repetition. These guys are doing it far more than I ever did...
It's amazing how protective I've been with my MBP's. I only got my first one a little over three years ago, have gone through four models in that time as my needs changed. And every one I baby with all my might. I like the finish, and I make sure I keep it as nice as I can. I have a Moshi palm protector on it to keep any marks from my palms from mussing it up, I have a keyboard condom from the same company since historically my laptop keyboards are either letter-less from so much use, or worn so smooth they shine like polished brass... So I'm glad that the local store took care of it.
