The background module scales based on the content and the image is scaled. You can get the full unscaled image, but you need to play with the height and the padding of the module or you get to see borders around it. Starting point is this CSS on the main element of the module.
Note: this may move the image below the content.
background-size: contain;
height: 352px;
Code language: HTTP (http)- better option is to add this to the CSS of the main content.
> min-height: 400px !important;
