I disagree – I think that no such perturbations exist in general, rather than that we have simply not had any luck finding them.
I have seen one such perturbation. It was two images of two people, one which was clearly male and the other female, though I wasn’t be able to tell any significant difference between the two images on 15s of trying to find one except for a slight difference in hue. Unfortunately, I can’t find this example again on a 10mn search. It was shared on Discord; the people in the image were white and freckled. I’ll save it if I find it again.
That one seemed pretty obvious to me. Angle of the hairline, sharper shadows on the nose to give it a different shape. Smaller eyes and head overall (technically looks a bit larger, but farther away). Eyebrows are larger and rougher. Mouth is more prominent, philtrum is sharper. Angle of the jaw changes.
That’s what I got in about 45 seconds of looking it over. It was an interesting exercise. Thanks for sharing that link.

(I’m writing a post on cognitohazards, the perceptual inputs that hurt you. So, i have this post conveniently referenced in my draft lol)
Ah, Gio Scotti strikes again.
