Those X-wing shots have some visible matte lines in the original and a slightly different position but other than that they are not that different so I understand you won't bother, those two recomposites are extremely faithful to the original, quite odd actually as they never bothered to emulate the original composites so precisely elsewhere what I've seen.
About those laser bolts, I'm only sure about those who appear in the absolutely last shot before Vader's entrance as the position and timing of them is so clearly different but there may be more of them in there of course. It's just such a tedious thing to go through and I guess even more so for you, maybe it's only those who appear differently in timing and position that's worthy of a despecializing if it's bothering you.
