Yeah, I forget that some remasters, have to rely on SD material as in the case of Cowboy Bebop, they only had the CGI stuff in SD, while the main anime is in HD.

This shot feels like it was a digital animation, rather then done on cel.
Often times, I feel like they still need to DNR which makes it look like it has less detail in them.
DNR tends to be a bit of a talking point, when it comes to using them on animation.
