iPhone 17 Pro wallpaper blur issue with screensaver

In my new iPhone 17 Pro, if I go on the settings for wallpaper and have my screensaver and my wallpaper as a pair, but my wallpaper with a blur it just becomes one color instead of a blur of the picture

edit: it says iPhone 12 Pro iOS 18 but it’s an iPhone 17 pro iOS 26
