ARKit Face Tracking works in total darkness?

I’ve seen, mainly in discussions with AIs, that ARFaceTrackingConfiguration uses the same technology as Face ID and therefore should work in complete darkness. However, I haven’t been able to achieve this. Does anyone know if this is actually true?

I'm using an iPhone 16 to test, and the Face ID works well in darkness.
