Header Slider images zoomed on iPad Pro

Hello.

I’ve read numerous threads about this problem for background images here, but haven’t found a solution to my problem which is the same but then for “Header Slider” images that are zoomed in.

Slider mobile behavior is set to “responsive”. Adding the extra CSS for background image doesn’t work (I am not a developer).

Problem is only on Safari iPad Pro retina displays (works fine on other mobile devices).

Any tips/help very welcome!
