Most games look better moving than in screenshots these days. There are just so many little effects that improve the moving graphics, but barely show up in screenshots. Other important aspects of a game's look, like animation or physics quality, can't be captured in a still screenshot either.
Then there's the effects that can be unsightly when captured in a single frame, but look good in motion. Take wednesday's dirtbike screen, for example. You can see a plain ghastly bloom sphere in the sky on the left, but if you saw that scene in motion you wouldn't even notice it because the effect would have corrected itself in a few frames.
To top it all off, a compressed screenshot will always exaggerate blemishes like aliasing, and decrease the quality of textures and texture filtering. I'm pretty optimistic about how this game will look, and I don't even think the screenshots look that bad.
