Hey, I wanted to add some input from our experience at Wix, and inquire if this issue has enough data to identify and fix the problem.

After holding off serving WebP for webkit based browsers for a while, we recently decided to re-introduce WebP for these visitors, and already encountered several user complaints of images not loading on iOS.

All these images are single-color in the requested dimensions, and this can be easily recreated on any latest Safari/iOS browser. We have been instructing these users to replace the image with a solid color background, but it would be great to hear this is being addressed, even if it's an underlying OS issue.

Here is another example in addition to the ones provided by Eric above, let me know if you need more:

p.s. someone added another example of an image that fails to load in https://bugs.webkit.org/show_bug.cgi?id=219977 which isn't a single color: https://bugs.webkit.org/attachment.cgi?id=454255
