If you're interested 005, this recomposite was indeed used on page 305 in Rinzler's making of.
This is how starwars.com described some of it in their old article.
"Color Reversal Internegative: Opticals created on CRI stock, which had deteriorated, were recomposited in various shots including the Star Destroyer capturing Leia's ship and X-wings flying through the Death Star trench."
The effect is almost an exact match to the original shot, only the slightly different position of the background and the lack of mattelines tell the difference.
The other shot I pointed out is even more subtle with the mattelines being the only difference as far as I can see, "the black garbage" seen in front of the cockpit was oddly enough not cleaned up.
