im mostly convinced that the confusing rinnegan and rinne-sharingan differences are mostly based out of rushed planning towards the end of the manga. the only real difference is some rinnegan have tomoe and likely possess sharingan capabilities(exactly like sasuke's) since we know otsutsuki evolve continuously by eating fruit there is likely no incomplete versions of any dojutsu to them but rather an endless chain of evolutions. kaguya just possessed the most genetically evolved rinnegan we have seen(full tomoe,forehead,extremely powerful) for all we know there are possibly levels even higher than that.
