The Otsutsuki's natural eye color is white. That's all there is to it. The otsutsuki of the moon were Hamura's descendants (and thus had his Byakugan). We don't even know how Momoshiki and Kinshiki relate to this whole story or how they obtained their power exactly. Them having Byakugan proves exactly nothing.

Hagoromo has white eyes because that's the color of the Otsutsuki eyes, just like Kaguya's eyes before she got byakugan.
