It is an optical illusion. They are exactly the same color and brightness.

At most we can say they're the same numerical RGB values. Whether they are reproduced faithfully by the display device for the observer seems to be another matter.

It's implausible that a modern display would render the same RGB value differently at two nearby locations.

You must be fortunate enough to never have worked with a display that shifts color based on viewing angle.

I do have a nice IPS display, but I've certainly seen shifts from viewing angle. (CRTs were worse, because they really could have nonlocal effects from large colored areas.) However, like calibration in general, angle affects the rendering of nearby points equally. It might create a huge divergence of relative colors between users, or between display and print, but it can't create an illusion like that posted.
