But your probably right though in the general imagination TOS remains paramount(no pun intended). It's all very difficult though for the uninitiated to be a fan of a complex franchise like doctor who or Star Wars or LOTR or Star Trek or Harry Potter or whatever requires(these days) to have a large amount of knowledge of the material, real enthusiasm for said material, and usually you end up with a devoted fanbase that can talk for hours about the world of Harry Potter or the difference in Jedi vs Sith doctrine or how the Borg are better villains that than the dominion or who the best companion was for the Doctor. In a way fandoms become their own subcultures with jargon their own societies in which the general public has limited knowledge of.
But its not just about "insider knowledge" versus the "outsider"--in both TOS and SW-OT, those original productions left such a powerful impression in the popular culture landscape that all other versions have failed to live up to its effect, and in one way or another, new productions (e.g. NuTrek & Discovery) race back to the most important/popular chapters of the franchise. Producers are not just doing that for the "insiders"/die hards, but general audiences. Going back to those aforementioned most important/popular chapters only speaks to what is believed to be the best known, best chance for the franchise to survive.
This applies to Star Wars--TFA did not earn attention based on Rey or Finn, but on the idea of the "Big Three" returning. Rogue One jumps right back to the period before ANH as a direct prequel--you cannot help but think of what major characters and events are around the corner.
Remove the callbacks / mining the original/most popular material, and what's left is rather dried up--exhausted as a concept.
