I didn't know about film stock, regarding the WotW wires. That's an interesting example, because it really does put you in a bind: release a film "unaltered" but in a way that greatly betrays the original look due to poor duplication, or alter a film so that it is closer to the way it was supposed to and originally did look. I can't believe the wires were completely invisible, but I would believe they were less visible/mostly invisible. So getting rid of them entirely is actually betraying the original look, though only by a little.

Interesting example.

Unfortunately it is pretty unique. Most films aren't faced with this kind of decision, and, I might add, that anniversary edition is just one single release. It's not like the film always has and always will look like that on video, earlier ones got it right and latter ones will hopefully too.

So, it's not so much as HD scans revealing "too much" detail as much as it is that they simply happened to use an incorrect print as their source. This was exceptional in the film's history, as far as I understand, and not related to the picture quality of the disc.
