Yes, those images are not blurry, that's precisely the reason I described them as blurry. /s

If all you do is read things on a microscopic mobile screen, maybe the sizing didn't scale a raster image beyond it's native size. For those of us boomers that read things on screens with plenty of screen space, things get scaled with that fancy mobile first responsive layout so that images are scaled larger than their normal size.
