Some iPhone 4 showing yellow blotches on Retina Display?

Seems like some iPhone 4 users are unboxing their new beauties and promptly finding some unsightly yellow splotches on the ginormous Retina Display:
In the bottom 10% of the screen there are three blotches about the size of shirt buttons that discolor the screen a brown/yellow color." You can see a demonstration of that anomaly in the image to the right.
Apple doesn't have enough stock to do exchanges yet, but it sounds like some folks are going to be heading over to the Genius Bar to swap them for fresh, functional devices just as soon as they can.
Anyone here seeing that problem? Let us know.
