^I personally consider The Masked Singer a reality show myself (since it takes the whole season to determine the winner).
So did American Gladiators and any show with a season ending tournament of champions.
I think Masked Singer falls into the more game side of the reality competition series, where the game is more the focus than any extracurricular stuff (like on Survivor) and thus Mama Grizzly doesn’t qualify.
So I would say “it’s your choice," but consider the way the show is structured.
