I would just like to know what blendshapes are still 1-to-1 and which ones I may need to combine to match ARkit.
I found this website that compiles the (not very easy to see) images from Apple's docs.
Just following the names is mostly self-explanatory…
If you start with the Standard expression profile, it's nearly 1-to-1. innerBrowUp and cheekPuff (probably tongueOut) need to be merged from 2 morphs.
To bake the bone poses into the jaw and eyeLook, I had to export an obj+expression and re-import it as a morph.
The Extended profile has more to merge, but also some good morphs
