Well that's kinda what I am trying to say it does resemble a technique and Zetsu even used it to show Sasuke and Naruto what he recorded from Madara's revival and Kaguya's sealing. This is why I think its more than a simple dojutsu. However you do make a good point it does sort of resemble the Byakugan in ability but it does not let Zetsu see chakra, or anything remotely similar to the Sharingan.
