Some of those looked good. IMO, most of the shots of people had marginal improvements. It seems like where this might be useful is if CBS/Viacom rescanned the original negatives, then just upscaled the SFX (assuming they weren't overbuilt as was the case in some instances). As it stands, DS9 is simply unwatchable for me on the DVDs and Netflix.ExtremeTech tackles upscaling DS9. Lots of comparisons with both OTT and MKV sources.
