The illustration also contradicts the real picture of the sensor.

Also from the same DPReview article: "Curved image sensors mimic the human eye", that illustration is not how I thought the retina is shaped.

The image of the sensor held by the fingers looks concave.

The illustration with simplified optics shows a convex sensor.

Hard to figure it out.

I would imagine chromatic abberation and light dropoff is due to flat sensors and concave sensors would help. But I might not understand modern lens design.
