Yea it's probably to have a catchy name and get some attention. Although it's technically accurate to call it 4D since it includes time, I think 3D video recording would probably get the point across to more people in a less sensationalist way.

Is it technically accurate? Seems like its actually 6Dof view angles + time. The paper mentions 4D view, 4D point cloud, dynamic 3D scene and 4D feature grid.
