Unfortunately, you're highly unlikely to see an official remaster of Star Trek: Deep Space Nine. Its special effects were shot on video rather than added to film, making an already daunting remastering process that much more difficult -- and since it's not a tentpole show like The Next Generation, CBS might not consider it worth the effort. Machine learning might make it easier for fans to fill the gap, however. CaptRobau has experimented with using AI Gigapixel's neural networks to upscale Deep Space Nine to 1080p. The technology is optimized for (and trained on) photos, but apparently works a treat for video. While you wouldn't mistake it for an official remaster, it provides a considerably cleaner, sharper look than the 480p original without introducing visual artifacts.
