The newer EVO's have recently just come out and there is a huge difference in the colors of the LCD screens. The newer model has a washed out look to it and the older has better contract, the colors are richer. If you look close to it you can see a row of dead pixels that can look like hair from a little further back.
The AMOLED displays, made by Samsung for the Incredible, has been struggling in keeping up with its demand. The HTC might have been looking for new displays elsewhere if these two events are related. But whoever is making the new LCD screens is causing the quality of the phone to suffer, using inferior materials. This might hurt future sales of the EVO, including the white one due to release in July, if you have two EVO's, it's recommended you check both of them for the display issue.
