Bah nope, found the difference:

Last thing –

If someone wanted to run this site wide, this:

add_filter('acf_the_content', function($content) {
    if(!function_exists('slb_activate')) return $content;
    return slb_activate($content);
});

Might be worth considering building into the plugin by default? Seems reasonable, since according to the team, acf_the_content only varies from the_content when required for a couple bugs, so their expectation is that your logic runs on them.
