Of course, using a tape source could never be a full substitute for DVD. But there may be quality differences for the available tape sources - noise, color reproduction, picture area, and audio - that may help.
I only mention that because I tried a quick color correction on your original DVD screen cap (page 1). Neither RGB nor color-wheel adjustments easily yielded results to exactly match your accompanying VHS cap. That might suggest an HSL recombination (Hue & Saturation from a tape source; Lightness from the DVD) to be a better workable process. It would look something like this (the added red border hi-lights the tape-source edge):
