I don't think the data requirements are that realistic. While the actual interference patterns on a hologram would be ridiculously large to send as a bitmap, it's easy to compute the interference patterns for the superposition of points of lights, which is what this volumetric display is showing anyways. So a computer would only need to send a list of points and colors to the display.

You still have to drive the display. If you are just sending minimal information, you then need something to process that data and output the 12 terabits/sec.
