I tried WebP because lighthouse heavily pushes it claiming big size reductions, the asterisk for those claims is of course way worse quality. Visually identical quality to JPEG only gave irrelevant improvements or none at all - 10 % or so are not worth the hassle over JPEG. Lighthouse also pushes WebP for PNGs but that of course falls flat on its face due to chroma subsampling. Maybe WebP is better than JPEG at low quality levels, but that’s not something I care about, what with not being in the streaming video biz.
