Unfortunately this hasn’t been done for others like Deep Space Nine and Voyager, which came after TNG’s run.
The reason for that, by the way, is that while TNG was shot on film (from which more detail could be extracted using new technology), DS9 and Voyager were at least partially mastered directly on videotape (especially the CGI effects) and thus there was no higher-quality source to pull from to begin with.
