Just received my brand new 27" 5k iMac, the computer is beautiful and so is the display, until you look closer. I am a graphic designer so I stare at images on the screen all day. As soon as I booted the iMac up for the first time I noticed a backlight bleed issue on the bottom right of the screen, I wasnt even looking for it and i could see it. Under closer observation I have about a half dozen stuck pixels up and down the right side of the display. See images, I made a Genius Bar appointment for Sunday and I can't believe this screen made it past quality control.

Anyone else?

That's a lot of stuck pixels. I wouldn't find that acceptable. Light bleed is hard to tell from that image since it's massively over-exposed. Some bleed is expected, sadly, with IPS displays, but that exposure level isn't telling the whole story.

It does look worse in the pictures, the only spot I can really notice is bottom right, which you can see is definitely the worst part of the photo. I can understand a little bit of backlight bleed, but to notice it on the boot screen and also to find about half dozen stuck pixels is pretty upsetting.

The screen looks gorgeous though and I love the new keyboard.

Hope Apple can just replace the display and I can move on with this gorgeous machine.

The boot screen is often set to max brightness. So it's not a good barometer, at all. I'd get a new machine rather than having them open the whole thing up.

Call Apple and get a replacement. Don't let a local store rip apart your new system.

Yup! No way I'd settle for a repair job on something so brand new and $$$, even if it means waiting a few more days for the replacement to rock up.
 
You should talk to them about that.
I think it's reasonable to ask them to cross ship.
So you could use the one you have until the replacement arrives.
Did you get Applecare?
I only ask, because in my experience they often seem to be more generous with Applecare customers.

No I just have the 1 year warrant and 90 day call support
 
funny thing is this display is the most uniform white i have ever seen on an iMac, usually they have that dark shadow on the bottom lol, but the half dozen stuck pixels and back light bleed on the bottom right kind of kills it
 
UPDATE: Apple ordered me a new BTO iMac through the Apple Store and let me keep the old unit until the new one arrived. When it arrived I just swapped the old for the new and before I left the store I throughly checked the display, and its perfect, no dead/stuck pixels or light bleed.
