It might be world space normals. Any docs?

indeed
https://docs.arnoldrenderer.com/display/A5AFMUG/AOVs#AOVs-AOVs

• N: Smooth normal at the shading point (in world space).

You can try adding a custom AOV, and then create a aiUtility node, change shade mode to flat color, and color mode to normal. Plug that into your custom AOV's shader option.

Picked this up from this tutorial: https://www.artstation.com/artwork/ZLGNG (at the very bottom)

Good luck!

Important Note to myself:
using front-facing camera, not the top camera
