@UltimaDude The eye markings came from Boruto's tattoo, Kawaki has the same marking from his but retains his normal eye.

Given the significance of showing the eye itself activating in its own panel, its safe to assume that Boruto's eye is special and likely because of Boruto's heritage and the way it looks its likely a Byakugan.
