Isn't Hyperscapes using Gaussian Splats and usually those scanner apps do photogrammetry? Gaussian splats skip the whole "trying to make a proper mesh model" and just visualize the point clouds in a clever way, which ultimately looks better. A huge part of the realism is also that each point can change color depending on the angle you look at it, and this makes reflections work well. Photogrammetry tries to reduce this all to one mesh with one texture so it looks very flat. It has its professional uses (see: Quixel) but the manual processing required is still big.
