This is really minor, and I don't know if the graphics engine supports it, but can't cockpit monitors have a little shading applied to them? Currently it seems that whatever color the pixels are in the virtual display, that's the color it is on your monitor, with no shading in between.
It's not really that noticeable in the Shark as it only has the ABRIS and it's doesn't look too bad on the Shkval screen, but on those preview shots of the A-10, the MFDs really stand out as a solid block of unshaded color, especially in the night shot where the rest of the cockpit is softly lit. It should be optional, as some people might prefer having a pristine screen. I know mods can add smudged fingerprints, dirt and whatnot as overlays, but that's different.
