It does look minimal and honestly the source files weren’t that bad. It’s just an attempt to upscale the image so it looks better on bigger screens. If you look at previous AI up scales and such there are lots of artifacts and things like that and this project is the cleanest I’d seen, but also things like stars and other small details are more clear or newly visible also
I like to watch trek on my big tv and the original source files are frustrating in that regard, so for you it may not be the same value and doesn’t make sense to replace an existing collection but for newer watchers may as well start at an improved version
