Well, I can actually see little to no difference myself, as apparently can Adywan, who also used the same picture to prove the same point. So maybe it's you :-)

I see no differences that are clearly more or less detail. The differences I see are slight ones in the shading, for reasons mentioned previously. And if I squint really hard until I make myself see something that may or may not be there, it just barely works. And then I look down and see that the extra resolution I imagined was in the 720p version.

Perhaps there is more to notice in an actual moving image? *shrug*

At first, the images looked so similar, I was hoping that it was actually a trick, with identical images, to make a point about the placebo effect.

It would make for an interesting game, actually. Release some unlabeled images from both versions and see if we can visually identify them.
