You can uncap the cutscenes FPS from 30, by unchecking the box in graphics settings. Don’t be me and beat ACT IV before noticing.

And audio effects for loot are really spiffy especially if you use headphones.
There’s also settings to play with toggles for channeled abilities as well.
It’s bizarre how they don’t quite understand this, because cinematics are Blizzard’s specialty. In order to do proper 24 fps (or even 30fps) that’s film-like they need to simulate the same kind of motion blur. To my eye, the in-game cinematics don’t use motion blur, or if they do, it’s not similar enough to make it look like a standard 180 degree shutter.
