I had a look at the homemade AI Upscale of DS9 and for the first couple of seasons….it’s barely noticeable. 

To the left is the AI Upscale to 960p, and right one of the DVDRips floating out there.

The problem again is you’re just doing it from the DVD rips and not the actual film stock so the same weird video wash is present in both version. It’s the limit of the technology. It gets a bit better when DS9 changes cameras/lenses somewhere around season 3 or 4 (idk exactly where, I don’t feel like checking every ep in between rn) and the native image is a bit crisper to begin with.

but here’s a comparison for way of the Warrior:

upscale:

regular:

The AI also has trouble with certain lines (they wobble or look weird) in the SFX, especially the jem’hadar ships lighted undersides that are far away or in Apocalypse Rising a bottom left section of Ty’Gokor wobbles a lot. 

It’s a valiant effort, especially for some eps that I had that had some choppy conversions to begin with (a rip of shattered mirror for example had choppy frames around some of the chases, the new one doesn’t). But it won’t replace an effort in-studio. just again a reminder of what TNG did:
