Does it work with super hi resolution phones?

I’m just curious if this has been tested with super-high-res phones? Like the Nexus 6P has a resolution of 2560 x 1440. Since this appears to not use any code to detect if it’s actually a phone or not, and goes purely off the CSS resolution, I’m just curious if it works fine on all phone sizes?

Would it be hard to add something like this: https://modernizr.com/docs/#features-misc to detect when it’s a touch screen, or something along those lines? I don’t want the plugin to get any heavier. But it would be nice to be confident it’s loading on all phones. Then again, I’m no expert in devices, so maybe the way you’re handling it is just fine.
