I think the DVD could do with some processing to remove video noise/grain, and because it has superior horizontal detail/sharpness the results should look better than any laserdisc transfer, despite the vertical blurring.

Yes, the loss of vertical detail could be the effects of a not so successful anti-aliasing filter. My guess is that the GOUT was then also sharpened and that brought some of the aliasing or jaggies back, or rather it emphasized the jaggies the AA filter missed. If it was sharpened it would also explain some of the higher noise level.
Since the D1 master already was DVNR filtered, the remaining noise really is a bitch to filter as it's full of the DVNR artefacts, the same also applies to the LDs of course. But it is usually also best to noise filter *before* any sharpening is applied.
I've not yet seen that much of the NTSC GOUT but I think it's less sharpened than the 'PAL'.
