It's the same source (amazon webrip) filtered differently. Mostly the webrip looks a lot better than DVDs, but there's also a lot less noise. Beatrice is pretty close to the webrip, while I've tried to get closer to the DVD noise level (as I think it's closer to the intended 'look').
I don't think still image comparisons work very well to highlight the difference in dynamic noise, so I'd encourage watching for yourself, but https://slow.pics/c/NuTOKy1l includes niizk as a DVD-based encode for reference.
