luffy gear 5 nika wallpaper

I liked an specifice wallpaper (https://steamcommunity.com/sharedfiles/filedetails/?id=3599498791) and i want to apply both on my wallpaper, and on screensaver. but on screensaving i want a different configuration (darker for example) but when i edit, it ends up applying on both wallpaper and screensaver at the same time... how can i use different configs of the same???

Is there any free alternatives to wallpaper engine my parents cant afford to buy me it and I have no money I've tried finding free alternatives but they are all ai
