The veins that Pop Out are the sign of activation of Byukgan. The white eyes could just be because of mating together.The Byakugan was never unlocked. If Kishi changes this then it is BS because it goes against the purity of the Byakugan lineage.
I can jump on the tenseigan hype train 'tho, we don't know much about it, except that the byakugan or maybe some byakugan (traits via blood, hamura chakra..) connection is needed but even this would be in the category of asspull.
Anyways I feel that Boruto will unlock some type of eye wether it be the Byakugan or the Tenseigan.
