Parallax background image on iPad is too zoomed in

The parallax images on my site are working properly on all my devices, except for iPad pros in landscape mode. On mobile devices, the parallax effect is disabled, and the image displays appropriately. However, on iPad pros in landscape mode the image is zoomed way up and badly pixelated. I was hoping to fix this with custom CSS, but am unable to find a solution that worked. Link to example page: https://www.relyence.com/products/fmea/. I’ve attached screenshot of image from iPad. Page renders fine on all other devices – I could not include more than one screenshot attachment below, so just attached incorrect image.
