I can defiantly see a difference, I'm at work and don't have a calibrated monitor. The top one's colors are much nicer. I wonder if it might make more difference on a cheap un-calibrated monitor?
I thought the same thing but it turned out my laptop monitor displays colors much better at the top of the screen, whereas the bottom is a little washed out, due to the backlight position (also viewing angle).
After looking at both images side-by-side, on my 24" monitor it's much harder to tell a difference between the quality of them.
