the other three aren't wrong, it's just an incomplete list.

my ddg default gave me the fictional character's wikipedia article as the top result (it lists all of them and what title they were in).

a vanity fair article praising momoa's work in the 2021 film was second, followed by the dune wiki character page and then imdb's 2021 film page was fourth.

i also have firefox keywords to search the wiki or imdb directly if i choose to, and that's what i would have normally done here.
