I would have expected the number of photo receptors to be closer to 20M per eye since resolution is roughly inversely proportional to the distance from the fovia (center of vision), and the information within a radius of ~2.5 deg of the fovia is equivalent to about a 4 MP image.

There are 120M rods (scotopic) and 6M cones (photopic vision). The optic nerve is made of 1.2M axons. So, there's indeed a 100× compression. On the other side, yes, you have 6 Mpx image with 3.8M DPI in correspondence of the fovea.

Why should it be this compression specifically that causes this illusion?

The retina performs a local contrast normalisation to get rid of constant values, since they do not carry information about edges of objects in a scene. You basically go from the top histogram to the bottom one in the figure below.pic.twitter.com/Jlxrrxm6tZ

Wow, thank you; I never realized that it can be actually printed out!! Just printed a few for my class this semester :) It's rad!!
