After having read some feedback on this scene, it seems that I was not the only one who thought that the surroundings benefited the most from whatever new set-up or technology VRB was using. I was most impressed by how sharp and detailed the city and skyline in the very far background looked.
Not knowing the first thing about video photography, how is it possible that filming in 12K alone can lead to such a result in a downscaled 8K video? Wouldn't you rather need improved optics to achieve such improved depth of field? Just wondering: Could it be that the whole 12K thing is just a decoy or marketing stunt and the actual breakthrough lies in another area (from which current standard 8K/6K filming could benefit as well)?
