The process was not a simple "push button, get 4K." It was a multi-stage, computationally intensive workflow:
The following report provides an analysis of the AI-upscaled version of Star Trek: Deep Space Nine, Season 1, released in 4K resolution in 2020.
Pair the upscale with a modern media player like VLC or Plex with tone-mapping enabled to get the best color reproduction on an HDR display (the file itself is SDR, but modern players can simulate it).

Furthermore, Season 1’s DVDs are the most compressed and artifact-ridden. Thus, a successful upscale of S01 represented the biggest leap in quality. Later seasons (which had slightly better DVD masters) would be easier, but S01 was the holy grail.

In 2020, the "story" of upscaling Star Trek: Deep Space Nine
Unlike standard upscaling (which just stretches pixels), AI upscaling "hallucinates" missing detail. The team trained the AI on thousands of frames of HD Star Trek content (from TNG Blu-rays and Star Trek films). They taught the neural network what a Bajoran ear looks like in HD, what the texture of Odo’s bucket should be, and how to resolve the blurry edges of the Cardassian monitor interfaces.
When CBS remastered The Next Generation into HD in 2012, they had to physically hunt down millions of feet of original 35mm film negatives, re-edit every single episode frame-by-frame, and entirely recreate the computer-generated visual effects from scratch. It was a financial gamble that ultimately did not generate the Blu-ray sales the studio expected. This link or copies made by others cannot be deleted
Star Trek: Deep Space Nine premiered on January 3, 1993, as a spin-off of Star Trek: The Next Generation. The brainchild of writers Michael Piller and Rick Berman, the show was designed to explore the complexities of the galaxy through the eyes of a space station's diverse inhabitants. The setting, a massive space station orbiting the planet Bajor, offered a unique blend of action, drama, and social commentary that distinguished Deep Space Nine from its predecessors.
