In the end, you can find an AMOLED dark wallpaper from the internet to go with this theme since it doesn’t have any good wallpapers on board. It comes with its installer, so you can open it, select Export, and then click Dark Theme. It converts your Windows into a completely black color, which you don’t get on the default Windows personalization settings.
If you’re a fan of AMOLED black, you’ll love the Pure Black theme on your Windows 11.
