I have an extremely hard time perceiving any difference on a 27" 4K monitor. I am not even sure I really see them.
The examples are just bad. If you want to show something, screenshot and enlarge it to show the artifacts.

WebP image gradients just looked broken (posterized) except the lossless one, which was (obviously) perfect.
One might argue that if you need to enlarge it to see the artifacts, then the artifacts aren't perceptible enough and the codec is already good enough for the use case.
The difference is in color around the edges of the picture in the background change noticeably on a non-fullscreen image on my Android 12 device.
Yes! Where's the red underlines and diffs? I can see the background banding, but the foreground looks the same at a glance except that some of them look ambiguously "off" in ways that could just be placebo.
You'd think a visual artist would be more interested in visual communication and not just a wall of text with un-annotated photos.
After that it was pretty obvious what the author is talking about.
