Putting the whole "Color Scheme" Aside, atleast when it comes to the concept design, it closely resembles to the byakugan in the incomplete circle where the pupil would be. Boruto Dojutsu definitely holds more relation with the byakugan than anything as new ordinary dojutsu . Though this might be a variant of the byakugan it isn't "The" byakugan. From what we know they share one trait and look similar.

One thing that sticks out about his eye is that it has a darkened sclera. Why is this?
We know in the upcoming episode, Boruto will have a dream of someone who was described as a person with
" an intriguing robe, with beautiful white hair and pale white skin"
It is 99% confirm that the person is an Ootsutski showing Boruto the eyes power. IRONICALLY Momoshiki in the movie version looked very similar to the one Boruto has.

Perhaps his black sclera ,may also ties in with the CurseMark user and that orochimaru is the cause of this demonic chakra that keeps possessing people in boruto. This really explains why mitsuki is interested about borutos eye and possible relaying the info back to orochimaru. Keep in mind, Mitsuki may also be Ootsutski related when he can senses dark spirit chakra the same way Boruto can see.
