Ryan,
You are 100% correct and that is exactly my problem too as I said in an earlier post "the real issue is that the yellowish screens have poorer contrast, color saturation and seem washed out when compared with the bright white ones like I have and also some on the store display".
I think that most people concentrate at the more apparent yellowish look, but in fact they are bothered by poor contrast and not deep blacks or correctly saturated colors.
Just to make things more confusing the new 3GS has improved text display so it is more difficult for most to isolate what they really don't like about the yellowish screens "Apple says that fonts on the iPhone 3G S are rendered by the phone, as opposed to being bitmaps, and that this approach accounts for the smoother and sharper appearance of text" excerpt from the Washington Post review:

I and my wife find the white screens (on our original 3G that we had to exchange 5 times when they first came out because they also had yellow screens) a lot easier to read long term. While the yellowish screen with poorer black may appear "easier on the eyes" at first, in fact it feels that it strains our eyes after 10-15 minutes of use as the blacks and colors seem washed out.
Please let us know how the blacks and color saturation look on the yellowish screens. Thanks!
