Oh for gawd sakes, I can't see 3D in this show being of any value at all, other than raking in a few more bucks because people are curious. The whole thing is just one big gimmick, and it has absolutely no importance. I'm for them tweaking the visuals as best they can, but why go over board? They are talking about 3D now just because it's popular right now.
They should just do some kind of restoration if they're going to do it, and then be done with it. And if they never get around to doing that, it's not like TNG isn't fine the way it is.
