Had my 27" iMac for almost a year now, and i just noticed this distortion/flaw on a reboot. It is apparently visible 100% of the time, much easier to see on a dark gray background. Its like a smudge/crack but under the glass, hard to explain. Just a darker "crack" looking area. Here is an iPhone pic.

any idea what this is?
 
Looks like a dust problem, do a search. Mine is one year old and flawless and has been opened up a few times too, not may not be so lucky.

Definitely not dust, and it has never been opened... have an appointment at the apple store, it definitely seems to be an LCD issue.
 
If you have an appointment with Apple, why not wait and see what they say? Always best to report facts rather than conjecture.
 
Almost certainly dust and you don't have to open up the case to get it. See this thread for how folks have dealt with it, in or out of warranty.

Someone posted a picture that looks exactly like my issue. This person opened up their iMac and cleaned it, and it was not dust. Like his, mine is best visible on a gray background, and not visible when white.

I posted asking if someone knew what it was without having to take it into Apple initially. You never know, maybe it is a simple fix other then replacing the LCD (which sounds like what it will have to be).
 
I am sure the Apple guys will fix it for you, they are great, the best repair service any company can offer.
