I use PIL (Pillow) and OpenCV to do static image rendering in hydrus, so if either of those add good WebP support, I can probably add it in a week. Last time I checked, support was spotty, like they could only encode but not decode, and complicated stuff like animation was completely off the cards. A quick look again just now suggests the situation isn't all that different.
I am all for new image formats, particularly if they can do higher colour depth like HEIF, but I can't add them easily until they become non-memes and get proper common library support. Or if you know of a python library I can easily get on pip that'll decode a webp to some kind of bitmap, please let me know!
Also, can you point me to some webps online so I can test out some real world examples, or are you looking for a different outcome here, like 'I'd like to convert all my jpgs to webp'?
