Att iphone 4 screen colors dull, way to fix?

[baseballbert]

I just got a 32gb 4 to replace a 16gb 4. Colors on the 16 were a lot deeper/rich. Set them at same brightness and there was definitely a difference.

Any way to recalibrate screen?

Might be defective. Call AT&T.

It's been known some screens will show differently. More and likely made from a different plant.
