Safari seems to not currently support the type option, which allows new image formats like webp to be used while specifying a fall-back image in a more well supported format like jpeg or png. 

background-image: image-set( "foo.avif" type("image/avif"), "foo.jpg" type("image/jpeg") );

The relevant part of spec is here: https://drafts.csswg.org/css-images-4/#image-set-notation
