I could pull outta my ass that the third eye was in fact the Byakugan, but a super duper ultimate version of it. Because that's what you guys did. You were shown her eyes (A,B,C) and told that she could use Byakugan and Sharingan. What you did was attribute AB as Byakugan and C as Sharingan, without her even having had any Byakugan activated there and an arrow pointing at her forehead with a "Sharingan" next to it.

The only activated eye she was shown with was the third one. For all we know, she might have had both Byakugan and Sharingan in her paired eyes and the third one was something else like Rinnegan.

The whole point is that we don't know, but it's you who act otherwise. There's no evidence either way.

Madara specially says the third eye is what casts IT which means the Third eye has to be a sharingan

also before hagoromo mentions that she has byakugan and sharingan neither her eyes nor her third eye are active in fact the third eye is completely closed when it he says that she had the byakugan and sharingan the third eye is open indicating that Kishimoto is saying that the third eye is a sharingan
