I think you are oversimplifying. The IR camera isn’t detecting “warm” (it’s not a FLIR camera), it’s detecting color in the IR range, which is going to be extremely characteristic of a face. In addition, a mask may copy appearance, but it’s not going to copy physical shape in detail. Finally, the channel between the sensor and secure enclave is likely encrypted and/or authenticated, so you can’t just inject any depth image.

"it’s detecting color in the IR range," A very narrow bandwidth of IR thanks to what we term the "Infrared Window," which is trivially easy to duplicate or fool, as it's one of the same IR bands used for surface mineralogy done via satellite. I'm really not oversimplifying at all; I am applying knowledge in fields in which I am competent to say "You think it can't be that easy, here's how easy it can really be."
