I had the exact same issue ("ghosting"), found it was an LG screen (which are known to have this issue), went to the Apple Store, and got it replaced under the guarantee. Just had to show the issue once, no further questions asked. Got it back with new screen after 3 days.
This was in Switzerland. Would be surprised, though, if they had such drastically different replacement or repair policies for such an obvious issue.
