I feel like the Rinnegan is the mutated version of the Tenseigan, like how the Sharingan could be the mutated version of the Byakugan. So Kaguya technically did have the powers of the Tenseigan, but she's one level above, which is the Rinne Sharingan, or in other words, the mutated version of the Tensei Byakugan. Where the mutated version represents the God Tree side, and the "pure" version represents the Otsutsuki side. I don't know, it makes sense to me this way.
