i love how you say"it has never been stated that she had the sharingan but then disregard that they never once say she has the Rinnegan" logic would dictate that having the power of the sharingan is the same thing as having the sharingan. in the same manner Hagoromo never said she had the byakugan either then since he said"beside the byakugan my mother had the power of the sharingan" having the sharingan and having the power of the sharingan are the same exact thing. if she had a Rinnegan Hagoromo would have said so. people assume she has the Rinnegan because sasuke saying a "genjutsu cast with the Rinnegan can likely be broken with another Rinnegan" thats not saying that kaguya had the Rinnegan. Madara had the Rinnegan and therefore any genjutsu cast with his eyes are by definition a Rinnegan genjutsu. Hagoromo said that his mother had the power of the Sharingan and with it she created Infinite Tsukuyomi. he never ever once says she had the Rinnegan and the manga never once calls her third eye a Rinnegan so its actually incorrect to refer to the eye as a Rinnegan since they have never once said its a Rinnegan
