This reminds me of the Star Wars special edition. "Only" about 1% of the movies have been affected, so what's the big deal? Well, plenty.
I liken the Star Wars trilogy changes and now season 2 of TNG to a beautiful new sports car that's been gauged along the sides by a key. Yes, the engine still roars, the seats are just as comfortable, the suspension still feels great, but the joy is gone because it feels ruined. Even if I do my best to look away from it, I still know it's there. IMO, anyway.
Some say the season 2 effects work is no big deal. Some say the Star Wars special editions are no big deal. I disagree.
Yeah the SEs were pretty bad, but that was a case of new CG effects being inserted into a movie from the 1970s. The difference in style was jarring as hell.
Here we're just talking about model shots that maybe aren't composited as perfectly as they could have been, and may not look movie-quality, but are still pretty damn good
for a scifi TV show.
And most important, they still look consistent with the series they came from.
