The image rendering on the File page doesn't use a HiDPI srcset, causing it to look rather pixelated on HiDPI displayed, especially when coming from a page where a thumbnail is shown of the image.
And thumbnails do use a HiDPI srcset, and I bet a significant amount of traffic to file pages comes from clicks on thumbnails.
