I know this is something Apple FaceTime does. I recently noticed that when I looked at myself during a video call it looked like I was making direct eye contact, whereas when I looked at the camera it looked like I was looking away. I thought maybe I was imagining things but I found this article to back it up: https://www.fastcompany.com/90372724/welcome-to-post-reality...

There’s also a video where someone shows how your eyes get distorted to cause the effect, but I can’t find it right now.
