I'm just spit balling here, so take what I say with a grain of salt. But, the loss of detail from the logo you posted
and what it looks like on the plane could possibly be how you have your graphics set up for in game. If you have it set more to
the performance end, that might be a cause.
Also, if you don't already try turning AA (Anti-Aliasing) on to 2x take another screen shot and post it. See if there is any notable difference.
By the way, there is some HTML code to get rid of that white box and to make it just stick to the plane without the white box. But, I don't remember what it is or how it was done. I'm sure a squad CO should be able to come in here and help you out more.
