Thanks to this weeks episode of Naruto Shippuden we find out that Ashura(a non Jinchuriki) has chakra avatar state in the same color as the "supposed" unique chakra avatar mode of Naruto and Minato.

So this proves once and for all that the chakra mode form and avatar state is like my theory suggests is unique to the Ootsutsuki Direct bloodlines(Senju, Uchiha, Uzumaki, Hyuga, Kaguya).

And because Minato(who is supposed to be not related to the Senju) has this UNIQUE mode and form is now officially confirmed to be a secret member of the Senju clan of the forest.
