I've opened up mine today since I had some bleeding and I noticed it goes away when pushing against some spots.
You just have to remove the screws and then rip off the front cover.
There are some clips on that so get a bottle opener or a not too sharp screwdriver to push the plastic in a bit and loose the clips so you can lift the plastic.
I now have it here without a cover, doesn't really look that sexy but whatever.
Now some new calibration profiles without the cover pushing on the panel and a cleaned panel.
All done with about 12 clicks from lowest brightness.

Did that with a Spyder 4 Elite which I borrowed from a friend.
And holy cow I also had some stuff burnt into my panel! The browser bar and the vel: from Counter-Strike: Source when enabling cl_showpos 1
The browser bar went away after 10 minutes and the vel: took a bit longer.
The burn in is not related to overclocking, happens with 60Hz aswell.
Even with all these little flaws and the risk of getting a crappy panel it's still worth it to get one of these.
For consistency: Got mine from green-sum with 1 dead pixel at the bottom left and minor bleeding which is now gone when I removed the front cover.
