But we know ANH by heart, we’ve probably seen it hundreds of times, of course even unused footage of Red and Gold Leader would be noticable to us, especially being aware the actors are much older, (one being deceased) to someone not familiar with the SW movies, I don’t think they’d see those shots of those pilots as any different than any of the other pilots. They made an effort to use the same utilitarian graphics and computer panels on things in this film. Many of the Imperial officers have the same sideburns and such as ANH and that era. Saying a film looks like the 70s would likely be a compliment.
This might be the curious feeling I… felt: 70’s footage into a 2010’s movie. It was like the ROTS trailer that used alternate footage of Ben telling Anakin story in ANH. The images don’t mix well.
