It's probably a misalignment problem where one or more elements in the lens are skewed causing the focal plane not to be parallel to the sensor.

See https://en.wikipedia.org/wiki/Scheimpflug_principle

How come it occurs in all 4 corners then?

Does it? Does it in my example?

IDK but shifting an element to one side should have an asymmetrical effect. Or else you are saying an element is too far forwards or too far backwards.

I would like to see a proper brick wall test from someone else.

It would help if we could see your test. Without that, it's difficult to take this any further.

Alright, I will post in a few hours when I have access to the photos. Can't post them right now.
