When I watched the 4k 60P version it "auto" played back at 360P and looked impressively smooth.
When I watched the "original" version it "auto" played back at 480P and looked familiar.
When I watched the 4k 60P version with it purposefully selected as 2160p60 it looked impressive, but had numerous *jump* frames where the motion interpolation seemed to choke. Nevertheless, the overall effect seemed very impressive.
