Why do you need the Dark Theme on Fire tablets?
Dark Theme, aka system-wide dark theme, was officially introduced in Android 10. It allows you to show content in a dark background on the screen.
Fire OS 8, which is based on Android 10, implemented the Dark Theme on Fire tablets without messing it up.
