The 2017 DS9 documentary “What We Left Behind” included ~2 minutes of an AI-upscaled test scene (funded by fans). No official remaster exists.

In the 2020-era encodes, facial textures—like the intricate crags in Gul Dukat’s Cardassian neck ridges—gain a level of depth that makes the show feel modern.
