Well, you can't really restore detail where there isn't to begin with. On its own merits, the GOUT can't ever substitute a 35mm film source. A laserdisc master just doesn't have that level of detail to begin with, but it especially doesn't when you take that master and blur it up to get rid of the grain. Maybe one day software will be advanced enough to "create" enough on a guess that it could accurately resemble what a high-definition image would look like, but could you still even consider that the original anymore?
