There has been a point missed.

For epubs, the cover image is created by rendering the first page. So, while the cover image size is important, just as important is how it is shown in the page. From the original screenshot, the cover images are just on the first page using an img tag. And there is nothing there to resize the image to fit the screen. Using calibre to add the cover will use an SVG wrapper to resize the cover image to fit the screen.

The other thing is that looking at the covers, they appear to be simple text covers with the title and author on them. It makes me think that somewhere along the line, the cover images have been generated from the text page and added to the book. I wouldn't be surprised if the books still had both. I'd probably look at removing those covers and letting the text cover stay and the device generating the cover image from that. Of course, you would need to make sure the text cover did size properly.
