You're making an assimilation fallacy and falling to grasp the technical reasons such as proper deinterlacing, frame rate matching, ineffective motion compression, and generally poor upscaling techniques. If you decrypt and grab the pristine content of a 4:3 or 16:9 DVD, then process it properly through Handbrake or such, it will look fine. I did this purposely for a couple of rare old movies because the VHS and streaming copies looked terrible. The DVD versions in various regions are much, much better and came out as playable artifacts I can put on an 4K or 8K output device. They look cleaner than when I play these than with a DVD player because of the extra computational effort that went into the filtering during the transcoding process.
