Oh I agree, if you cant see it makes no odds. I was just trying to say it basically works this way, crap in crap out ie: if there's artifacts in the source you will see them no matter how great your gear is, thanks Mr Lucas. Its hard with Star Wars because you can only adjust its colors and so-forth so much, until some how we get a pristine scan of a pristine copy we'll have to put up with these niggles.
But once again i've never had an edition of Star Wars that reminded me of what it used to look like as much as this one.
