When you publish a post or a page with a gallery, the so-called “attachment pages” you get when clicking on each thumbnail adopt your default Settings, not the options you select in the post or page editor.
Whatever you change in your Settings will apply to posts or pages you create after you’ve made that change: it won’t affect already created posts or pages.
So the only way to have gallery attachment pages with no comment field is to disable commenting in Settings>Discussion before creating gallery posts or pages, (and override it in the Discussion module of the post/page editor for posts/pages in which you do want to allow commenting).(dll)
