How to remove Smush info from site admins' media library?

I would like WP Smush Pro to be completely invisible to site admins. I'm using a plugin to remove the admin menu item Media > WP Smush, but still visible in the media library is:

WP Smush
8 images reduced by 11.78 KB ( 3.8% )
Smush stats [+]

visible in the sidebar when an image is selected. Ideally, I would like to make it so only network admin can see it, such as current_user_can('manage_network'). What is the best way to accomplish this?
