ok as for Boruto having 1 byakugan. if it is indeed a byakugan and he indeed naturally awakened, there could be a reason for it. once kishimoto was asked what would happen if a uchiha and a hyuga were to have a child. would the child have both the byakugan and the sharingan. kishimoto stated that if that occurred the child would A have either the Sharingan or the Byakugan or B 1 sharingan and 1 byakugan

so Boruto might have some other Dojutsu in the other eye. or he could have just had it transplanted. as for the veins not being present that could be design error where the artist forgot to put the veins or it might not be a byakugan or it could be an enhanced byakugan. people with the tenseigan for example have no vein protrusion yet the tenseigan is an evolved Byakugan, maybe The mixture of sage mode and the byakugan results in a byakugan that doesn't require the veins to protrude

another thing. it might not be an activated byakugan. remember originally before we saw sasuke awaken the Sharingan in the original series. Sasuke was able to use the calculative abilities of the sharingan with it inactive, haku and zabuza were surprised that Sasuke could keep up and continue to to keep up. then sasuke activated his sharingan this indicates that dojutsu are someone always activated on a minor level. it could be that when the white eye itself is present there is some level of power granted and that the veins only protrude when it is fully activated. the veins could be there so the hyuga has 360 degree vision. if boruto has sage mode he wouldn't need to fully activate the byukugan from the start of the battle because sage mode grants 360 degree senses which brings me to my next point. sage mode would nullify the blind spot over the thoracic nerve. this is an interesting concept(sage mode plus byakugan) there would be no way to catch them off guard
