I think the other side of it for me is a completely different approach to those visuals. Star Wars, as you note, is a fantastical universe that was set far away from our current reality, deliberately so. There was no connection to Earth in any particular way. It was set up as an archetypal story. To misquote Yoda "You only find what you take with you."You especially see that envy for how Star Wars approaches it. Unlike Star Trek, that franchise actually replicates the sets as they looked from the 1970s, and they use deepfake/de-aging for dead or aging actors. "WHY CAN'T CBS DO THE SAME THING????"
Because Star Wars was made to look good on the big screen, so many of the visuals don't actually need "updating" (unless you're George Lucas), especially since it's set on a fantastical universe that's separate from ours. Whereas TOS was meant to be seen on tiny fuzzy 13 inch monitors with colors bleeding all over. No one in 1966 ever imagined people would be watching it 60 years later in high definition on a TV screen that is the same size as the bridge monitor.
Star Trek is completely different. It was directly connected to humanity of present day. And the technology and abilities to express that technology would be updated constantly. TMP is the most glaring example, but there are efforts to expand upon what technology was present.
What this often does is go against the idea that Star Trek is a unified whole in a way that it really was never intended to be. Star Wars does its best to be that bigger whole, but it was never connected to present humanity the same way.
