Is the yellow screen the same as the screen turning yellow at bottom?

Or would you guys say that it is a completely different issue?

My launch 3GS(week 21) and my replacement 3GS(week 27) both have the yellow tint at the bottom.

I received my 3GS a little over one week ago and it had a noticable yellow tint near the bottom of the screen. It also had a blue tint in the top right, near the battery indicator. I tought about asking for a replacement, but decided to give it a few days. I'm not sure why, perhaps burn-in, but the screen seems to have evened out. The yellow is almost completely gone. I don't think I would notice it now if I had never seen it originally.
