Unfortunately it tries too hard to enhance faces that are far away, resulting in distorted facial features.
Here is a frame that reveals the damaging effect:

Try using the newer model Rhea to see how that performs on this video as it is a mix between Iris and Proteus.

And especially try Rhea at 1x / original size.
This avoids most of the monster faces while still providing a great cleanup and giving quite some extra detail.

Rhea is even crispier than Iris and the small faces are somewhat better. Too bad it is so slow: 3 fps vs 15 fps.

Rhea runs at approximately 7 fps here (M2 Ultra) with SD sources.
