The pattern argument is case sensitive. Example:

<?php
$input = \Imagick::queryformats('PNG*');
?>

The PNG* will be included PNG, PNG00, PNG24, PNG32, PNG48, PNG64, PNG8

(Reference https://www.geeksforgeeks.org/php-imagick-queryformats-function/ )

If you enter png* then it will be return nothing.
