But the Byakugan might not necessarily be the origin of the Sharingan. As far as I can tell the Sharingan and Rinnegan came from the Juubi and the Byakugan came from Kaguya (Wherever she is from). In my opinion the byakugan is not specifically meant for seeing chakra and such, but it is the "all seeing eye" so of course it can see anything, chakra included. That's my opinion though. So in theory the Byakugan isn't from the Narutoverse that we know but rather wherever Kaguya came from. In saying that, Kaguya does have the power of the Sharingan too so it sort of did originate from her and indirectly the byakugan.
