I suspect also contributing is that the setting here is more like what you usually see with computer graphics than in real life. Very few moving parts.

In real life there are insects, and birds moving around. Wind blowing all sorts of things (leaves, blades of grass, trash, etc), etc. Individual strands of hair. Etc. All things we can't really reproduce with graphics.

Here there is just a sphere with a surface texture and some volumetric effects.
