Hmmm, to quote Spoons, "I don't think so, man."
I know the shine effect is basically a contrast-enhancer, but it looks great on all other ships I've seen so far. That's why I think the problem are the Excalibur's textures themselves... they must have more contrast than the others I've seen (Crossbow, for example).
Some of the plating lines are clearly darker, and the hull looks too clean - notice how most of the brighter areas look plain white, as opposed to what happened with the other ships, in which you could see the hull detail even in the brightest spots.
