Can I do $pagenow on query pages like admin.php?page=example?

Question

I'm working with...

global $pagenow;
    if(in_array($pagenow, array('example1.php','example2.php'))) {}

In Wordpress this works fine for enqueuing admin scripts on only their needed admin pages.

Is there a way to apply this same concept to query pages?

Example:

global $pagenow;
        if(in_array($pagenow, array('example1.php?page=example1','example2.php?page=example1'))) {}

There are some plugins I am trying to make load more efficiently in my set up but some use the page query for their pages and the above code doesn't work.

I'm not finding anything online for this.

You can do something like this:

if ( isset($_GET['page']) ) {
    global $pagenow;
    if( in_array( $pagenow, array('example1.php','example2.php') ) && ( $_GET['page'] == 'example1' || $_GET['page'] == 'example1' ) ) {}
}
