I’m going to be completely honest, and it’ll make me sound conspiratorial and a little crazy, but I actually don’t believe anyone that says they “completely” bought the CGI Tarkin. I’ll buy that they didn’t think it was CGI since the idea of using computer animation to insert a deceased actor into a film and give the model a prominent role is still pretty insane to most people, but there’s no way that they didn’t have a thought in the back of their head along the lines of, “This looks weird.”

EDIT: I’m going to make a thread about this in General Star Wars Discussion.
