I have exactly the same issue, it just started this morning with my 27" Imac- and restarting does not help. Any other ideas, apart from sending the machine back to the shop? Is it related to moisture? Monsoon's just finished here and as the original poster noted, it looks a bit like mist or condensation.. It's very distracting! Any other advice would be much appreciated!
I am facing the same..on my imac 24".. first time seen today
It's covering a big part of the screen and it indeed looks like condens/fog... .

Think I have this one since 2008 somewhere... too soon to die now.. :\
I shut down machine, let the large spot disappear.
So it seemed to be a heating issue then I thought.
Figured if it were the same issue as with an over isolated house without proper installation, it could well be a ventilation issue. So I vacuum cleaned every opening in case there would be any dust in any of the ventilation spaces block proper venting.
So far so good.. let's see how it keeps... .
I had this issue on 27" iMac. At first I thought it was dirt on the front glass, so I removed the front glass (per instructional videos on youTube) and found that the patches of grey were on the LCD itself. Careful lint cloth wiping of the LCD had no effet on the patches.
I took the machine to Apple Repair center, demonstrated the patches to the staff, and the LCD portion was replaced under warranty. By that point (6+ months after purchase) the patches covered around 30% of the screen, but only visible when the background image was displaying a white/gray/light color; the patches were not evident otherwise.
I'm not an expert, but I think this issue may be due to the LCD being incorrectly installed too close to components in the rear (or being loose), causing some kind of burn. Whatever the case, our monitors should not have color patches under normal operating conditions, so (in my opinion) this fix should be covered by hardware warranty.
