Nope. I think what you see is what you get. The design is exactly the same in both images, and I'll wager that the dark and dirty tone you see in the unmasked image is the result of black grease, oil and/or soot from being in a prior battle. I have a feeling this will look better on film, though, than what people are expecting, with the right lighting, effects and enhancements. But let's not kid ourselves, despite some minor design changes, Spider-Man's costume from the comics isn't all that different from what we see here if it were translated faithfully, which just goes to show you how silly-looking it is in real life. It's just one of those things we have to expect and accept in live-action if we want it to be just like the comic books.
