The images of the smaller Face ID and front-facing selfie camera cutout, instead of a still-smaller round hole punch for just the front camera, seem to add further evidence to the idea that Apple has figured out how to put not just Face ID's flood illuminator under the display, which is just a small part, but also the infrared camera that reads the dots that the IR illuminator projects onto your face. The IR illuminator will probably still be under the clear cutout that the front camera will be under, since Apple hasn't finished implementing getting that part to push its dot beams through the display layer wtihout distortion.
