^but so6p-chakra isnt the same as the chakra a rinnegan-user produces, afterall the so6p-chakra is causing the mutation, but the mutation ends in a different chakra form, this is why naruto didnt get the rinnegan despite getting so6p chakra,

i would say it is like this: sasukes own features (being indras reinc) + so6p chakra = direct awakening of rinnegan albeit in some mutated form (and the rinnegan is what makes him immune, not the so6p chakra)

narutos own features (being ashura reinc)+ so6p chakra = SPSM...
