At least it tells us he's not a Sith. Sith wear primarily black. I see the world cracking open if kids are suppose to digest that Darth Bane can wear a gold robe.
How could he have been anything but CG? His height, facial structure, and the portrayal that was established in TFA meant he would be impossible to do well any other way.
He should never have been a motion capture character in the first place.
