The eye has only been able to see the Chakra Flow, see the Chakra Pathway, and see through Barriers. So far, it's been similar to the Byakugan in every way. However,

"He also explained that the eye is related to the Ōtsutsuki clan's dimension and its powers are the dōjutsu equivalent of Naruto's ability to sense negative emotions."

This statement does not make any sense to me. Toneri recognized the Dojutsu. But if it's the equivalent of Naruto's negative sensing, that would make it a mutation of the Nine Tails and Toneri wouldn't have recognized it. All in all, I think this is connected to the Otsutsuki Clan, probably the equivalent to Mangekyo Sharingan for Byakugan. With how much Otsutsuki Chakra he's gained (Naruto has Hagoromo's Sixth Paths, Hinata Hamura's, and possibly Toneri's who was stated to do something to Boruto by Urashiki), he might have been born with or has the Chakra of an Otsutsuki.
