I mean, at its worst some days it feels like Trek assumes TOS doesn't exist.
For example, Rank structure derived by bars is only in TOS and the first movie. Everywhere else (including works that should predate TOS like ENT and DISC!) the pip structure from TNG is used. Gold at least is used for command in ENT and DISC if you wince, but everywhere else, it's red thanks to TNG. The Navigator station has been MIA since TOS also, replaced by "Ops".
These are little things... but details like that matter to fans like me. It feels like it's been a long time since there's been an installment truly connected to the Original Series. I'm hopeful for Strange New Worlds, which bills itself to be exactly that.
I understand those frustrations. For me, as long as the main plot is canonically accurate then I can forgive those aspects. But I think most everything since ENT has broken canon at some point.
I do love the new star trek though, especially since each show isn’t derivative of the same style. But hopefully strange new worlds scratches that classic star trek itch.
