I just did some googling and found at least one app to do exactly this on Android. This is now my phone background!!

(I used this, but it does leave a small "please purchase" banner at the top, until you pay: https://play.google.com/store/apps/details?id=com.nuko.livew...)

I use a built-in MacOS wallpaper called Solar Gradients[1]

It looks very similar!
