Welcome to Android Central! Does this happen with both preinstalled and custom wallpapers?

When you choose the wallpaper to apply, does it give the option for Lock Screen vs. Home Screen, like this?

I see your low on battery maybe system kicking in a power save mode and putting everything in dark mode because of it ? Does same happen when your at 50% or more with battery percentage?
