No variations of Byakugan?

[NarutoB]

Shebalso had the sharingan and the Fruit.

It wasn't a normal Sharingan was it? And she got that Sharingan from the fruit. She had the Byakugan before that though

Look at it this way, someone of her caliber would have awakened a higher form of Byakugan, right? Yet all we saw on her was the basic Byakugan, which makes me believe there is no higher form.
