It's... not? That's not what I was suggesting or asking. Kaguya's Rinne Sharingan was passed on to Hagaromo and gave rise to the Rinnegan. Hamura was the first confirmed person to have the Tenseigan, which is essentially equal to the Rinnegan in power and is awakened in the same basic way. So, logic would dictate that Kaguya would've had either the Tenseigan or a stronger equivalent- but canonically, she doesn't, instead having a standard Byakugan. This begs the question of why, and my personal theory is that she did have the Tenseigan, but was unable to reawaken it when she was resurrected.
