Too many services today do stupid image transcoding today. While the URL says jpg it will decide that because your browser supports WebP that what you really must have wanted was a WebP. It'll then either transcode or just send you WebP data for the image or send you a redirect. This is rarely what you actually want. With wget it sends you the source you actually requested and doesn't try to get clever (stupid). Google likes WebP so that means everyone needs to join the WebP cargo cult even if it means transcoding a lossy format to another lossy format.
