Have been taking piano lessons for almost a decade now (very committed), I can tell you most piano teachers are not going to care about this kind of gimmicks. Most teachers don't even want to bother with online lessons over Zoom or whatever -- you either go to their home for lessons on a real acoustic piano or you don't have lessons. Only the most eccentric teacher is going to spend $3.5K on this toy and expect their student to do so as well.
Music teachers don't dislike Zoom because they're reluctant to use tech in the abstract, they avoid it because trying to teach a music lesson with a bad mic, a half-second delay, and a low-FOV camera pointed haphazardly is a nightmare.
