The best situation is what happened in "The Drumhead" where a quick SD cutaway of the damaged warp core through a window in Engineering was substituted for missing footage. That one is very difficult to spot.
Yes, that one is really difficult to spot because of all the smoke in the shot and thus works really well. This is no substitution of different missing footage, though, but again, just upconversion of exactly the same SD footage.
