People call it a tenseigan due to the glow, but i don't see why that's any definitive answer.

Power-wise it's an extremely shitty Byakugan which can only see one specific chakra. He can't even see 360 degrees or X-ray. I think it's thus an underdeveloped Byakugan. At some point Boruto perhaps learns to control the eye and so eventually it becomes a proper Byakugan.

Also note that the Byakugan doesn't really have "Forms". Hamura's and Kaguya's eyes were called Byakugan, even though they were almost certainly vastly superior to that of a regular Hyuga. Unlike the Sharingan it's a physical eye, and it seems that manifesting powers via the Byakugan doesn't make it a new Dojutsu. IE the Moon Otsutsuki apparently had Byakugan that could draw in nature energy.
