No there's no dark mode theme, just the default theme. It would be nice if theme developers would make dark mode themes that actually worked with dark mode. Right now if you choose a "dark mode theme" (is what Samsung/Theme Store has it categorized as but those themes don't actually theme anything), it only changes the wallpaper and icons. It'd be nice if Samsung would make other colors of the default theme. I'm not a fan of the blue/green colors they are now. I'd prefer pink or an option to choose pink.
