On the other hand I find it the lamest and most annoying "feature" of the last 10 years. The article itself is a good demonstration (at least on my M1 MBP): as soon as an image has a single pixels row displayed, the luminosity of the whole page fades, and the reverse happens when no image is in sight. The comparison video is the first time ever I see the tech doing anything else than changing the luminosity of the screen.
