Image style with 800px width size is displayed on the xs (mobile devices).
Proposed resolution
Enable a new responsive image style breakpoint for the xs devices (1x screen-xs-max [all and (max-width: 575.98px)]) and use an image style with 600px width size.
Make the 800px style only displayed on sm devices (tablet devices or larger than 576px).
