I'm not sure this is particularly telling. You can write a tiny program that generates a 4K image, and the image could be 1000x larger.
Or, if I write a short description "A couple walks hand-in-hand through a park at sunset. The wind rustles the orange leaves.", I don't think it would be surprising to anyone that an image or video of this would be relatively huge.
