Following... I used to download the IPSWs, mount, and extract the wallpapers out of there, but things seem to have changed for iOS 16. I could only find the clownfish wallpaper, and the default one...but even then, they were broken up into multiple layers for the depth effect. There wasn't a flat image for those that I could see, nor did I see anything for the weather and astronomy backgrounds. They weren't in the location where the wallpapers are normally stored, but they must be somewhere.
