@Edent I'm reasonably confident Catherine's iPhone is the 12 Pro. You've already pointed out the camera cluster from the 11-15 Pro models, and Caius in the comments has rightly pointed out the pronounced LIDAR sensor in the lower-right of the camera cluster, which appeared from the 12 Pro onwards. I'd add that the camera cluster was made noticeably larger for the 13 onwards, and to my eye the phone in the picture has the smaller form factor.
