Bleeding is not image retention.

Sorry to hear that, I also bought a 27'' late 2012 iMac model at the same time as you, and there's still no IR here. I would definitely return a new iMac showing this flaw. Really strange however that IR showed up on your iMac screen after nearly 2 years... You should talk to Apple support, I've always been very happy with Apple's costumer service.

*sigh*

So far, it's only the lower right corner (which is where I saw it on a reboot), and after doing the image retention test - it's still that lower right corner. Interesting that it's manifested itself in just one corner...

Yep, it's a little strange. It's also just on the lower right side area of my screen. The left side is just fine.

And this is why I maintained it doesn't affect everybody. The iMac has been in the exact same place for not quite two years. Very odd..

I'll keep an eye on it, and I'll get the screen replaced under Applecare anyway before my 3-year warranty is up.
