Hi
With this growing problem with the display I am afraid to buy one
Is there any way to find whether the display is lg or Samsung from the box package before opening up
Looking forward
I think that everyone really needs to keep in mind the extent of the problem. Only you can decide whether or not this is a show-stopper issue for you but realize that even for people for whom the image retention problem is very easy to reproduce in artificial situations, it is almost never perceptible under normal use.
There are a couple of people who have posted that it's so bad for them that they see the image retention on colorful backgrounds like the galaxy background. But for the vast majority of people affected by IR, myself included, you absolutely cannot perceive it except on a flat grey or other flat color background within a limited range of brightnesses.
Most people are not happy just knowing that their display is somehow less than perfect, even if it's not actually tangibly going to affect them. And of course, there are some image professionals for whom even the hint of the possibility of image retention is unacceptable because accurate color reproduction is vital to their work.
For normal use, by normal end-users doing non-image-professional work, it is simply a minor inconvenience at most. I have used my rMBP very frequently since first noticing that it had IR on a flat blue background (the Windows 7 desktop in VirtualBox), and it has never once been noticeable to me except that one time, unless I specifically try to cause it via artificial use cases.
All that being said, this is clearly a defect and it's not something that anyone should accept (unless they truly don't care about it, which is fine as well). But it doesn't make the laptop unusable. It does mean that you have to take the risk that Apple will never fix it (which I think is unlikely), and that you have to probably live with it for a while until Apple can come up with a satisfactory, coherent, world-wide strategy to address it.
Alternately, you can choose to play a game of Samsung roulette which just seems to me to be an incredible amount of unnecessary hassle for all involved. I'd recommend waiting a couple of weeks/months and if Apple doesn't have a more customer-friendly way of dealing with this problem then we can all start making a seriously huge stink about this.
