For me, this is what has always made the V2 somewhat problematic. I tend to prefer idealized, but in this case the hero is the idealized version. I have a good hero version in my collection, but the problem with thinking of it as Luke saber is that mark Hamil never used it. In a way the Hero is Lucas's first experiment with special editions: even though it was before initial release it was still one of the first examples of plugging in a a later shot with a cleaned up look.
I'm in on the run that's happening now for the single part V2 and I'm still deciding how far to go with accuracy. The V2 really can't go full idealized, so where's the goal? I think I'll end up near where your posts suggest: acurate as possible paint, but I'm probably not going to ding up my prop.
