If your not in the cinematography world your never understand the clear differences between lenses for stills and lenses for cinematography.
On the whole cinematography lenses are as you would expect from the price are better at controlling chromatic abberations, dealing with flares and mechanically far superior. They tend to have more precise markings, T stop calibration, adjustment for back focus (normally through shimming), and MTF consistently example to example.
Most testing of cinematography lenses in the field is on special purpose projectors where were looking at field curvature, chromatic abberations, even field illumination and accurate lens makings.
When you need to fill huge cinema screen with sharp images from super 35 image area or vistavision the lenses need to be the best they possibly can be not forgetting many are overlaid with visual effects during post.
