Your estimate is using compressed video rates, which might be a argued way to look at the way that the brain processes and fills in presumably "already known" or inferred information. I don't know enough about this subject to make that argument. Uncompressed rates are easy to calculate if wanting to adjust your approximation: 24-bit, 4K UHD @ 60 fps: 24 × 3840 × 2160 × 60 = 11.9 Gbit/s.
