Yeah, I hate that too. The AspX is terrible, it looks like a shop that has just closed down in the wrong light. Which is a shame, as I love flying it.
The various shader mods around that get rid of the scratches also darken the display, I 've found. Not immediately obvious, but when you go and land somewhere dark, you'll see that the headlights are very subdued, and HUD elements look rather dull. After a while, you start to realise that everything has become slightly dulled wherever you are, and it's not something that is remedied by increasing gamma.
The scratches weren't as badly visible at one time; the lighting "upgrade" in 3.3 made them stand out more. The worst thing is that you can really see the repeating pattern of the scratch texture when it is so obvious.
