The only movie I've ever enjoyed after reading the book was Jurassic Park. I've never seen the Dune movies or most other book-based movies, but honestly The Martian and Project Hail Mary were tempting. I'll probably surrender to one of those two someday.
OP refers to details from the book that are not in either film.

Especially when the movie is over forty years old.
I don't think 1984 dune was successful culturally or financially. Definitely a different beast from the recent attempt, which has been wildly popular.
