> I opened the first two pictures in separate tabs and switched quickly between them. There is zero difference. Tried it on two different monitors, Chrome and Firefox. Same with the pictures of the guy at the end. One easy difference to spot is the background in this pair is posterized (https://en.wikipedia.org/wiki/Posterization https://en.wikipedia.org/wiki/Posterization) in webp but not in jpg: https://eng.aurelienpierre.com/wp-content/uploads/sites/8/2021/10/Shoot-Antoine-0044-_DSC0085-lossy-dithering-90.jpg https://eng.aurelienpierre.com/wp-content/uploads/sites/8/20... https://eng.aurelienpierre.com/wp-content/uploads/sites/8/2021/10/Shoot-Antoine-0044-_DSC0085-lossy-dithering.webp https://eng.aurelienpierre.com/wp-content/uploads/sites/8/20...

For clarity if anyone is still confused, on Wikipedia's example image, look at the snakes's shadow - that's what's happening to the background in the blog's image. I didn't know the word "posterization", so I'd describe this (slightly?) more simply as a stepped gradient instead of a smooth gradient.
