The "Art Optimized (Supersampling)" setting within Export For Screens > Format Options is not working correctly for any of the JPEG settings.
In the output, placed hi-res raster images are ruined, as if the "Type Optimized" anti-aliasing setting were selected.
Export for screens PNG format honors anti-aliasing setting, as user would expect.
Save For Web (Legacy) JPG format honors anti-aliasing setting too.
But "for screens" JPG output is broken.

[EDIT] admins seem to have merged this with another report of the same bug, which is fine except that our example images are now jumbled together.
