It's been a while so I can't remember exactly, but you used to be able to specify a different theme for desktop vs. mobile (like the old SmartPocket theme). You'd probably have to customize (or make a child theme?) of Bootstrap Darkroom to make Piwigo think it's for mobile only. Then you should be able to keep the Elegant theme for your desktop users and Bootstrap Darkroom for mobile.

Did you ever get this working? The solution you outlined seems to work for me. Specifically, I edited the Bootstrap Darkroom theme's themeconf.inc.php file, adding  'mobile' => true, to the themeconf array as shown below. Once I did that, Bootstrap Darkroom appeared in the Piwigo > Administration > Configuration Themes with the (mobile) label in italics. I am using elegant as the default theme for desktops, and Bootstrap Darkroom as the mobile theme. I like Smart Pocket for mobile, I just wanted pinch to zoom functionality the Bootstrap Darkroom's mobile theme offers. I found most people seem to intuitively pinch the screen to zoom , vs double tapping to zoom as in the Smart Pocket theme.

$themeconf = array(
    'mobile' => true,
    'name' => 'bootstrap_darkroom',
    'parent' => 'default',
    'load_parent_css' => false,
    'load_parent_local_head' => true,
    'local_head' => 'local_head.tpl',
    'url' => 'https://kuther.net/'
);
