Character sheets suggest that he always has it active. It was likely just omitted in the movie (as a normal audience wouldn't be able to see it anyway, and money spent on showing the Rinnegan is better spent on stuff that matters). I mean, he has it active at tons of moments where it makes no sense, why wouldn't it be active a the moment it does?

As to Madara, Madara was an Edo Tensei. It's not exactly representative of a person's real abilities. When Madara was alive, he never switched back to Mangekyou to Genjutsu someone.
