Thanks for posting that screengrab with the graphic, Burbin. It definitely helps understand what you’re seeing.
I think the reason you’re seeing that, for me, there was a lot of haze/mist in the shot that naturally would remove contrast from the objects in the scene, giving what would be black that light bluish tone. To me the shot always had haze completely over the X-wing, but the top of the tie fighter was peaking through the mist. I’d have to check but I think it was like this on the original shot since the two ties have similar profiles.
I’ll have to double check and see, though!
