As for kaguya and resent movie villians (Toneri and Momoshiki) has shown the byakugan to be the default Dojutsu of the Ōtsutsuki clan, which is the technically the ancestor clan of all ninja clans on earth, I’ll dare to say that all other dojutsus including rinnegan are nothing but a mutation of the o Ōtsutsukis byakugan. Yet the Tenseigan seems to be more like a chance on appearance, given when a byakugan user overflows with chakra, as Hamura surely did. Toneri’s tensigan had the be produced by merging and then absorbing the huge amount of chakra sealed within the Tenseigan Energy Vessel, being his chakra mode and truth seeking balls a direct result of the many different chakras within it. That is the reason, I belive, his tensiegan ‘’reverted’’ to byakugan after naruto defeated him, as his body wasn’t able to sustain that much energy any more.
