Samsung

I don't understand your issue. You have included a screenshot for Netflix.

Sorry for trying to help you.

Try turning Night Mode on and off.

Go to Settings > Wallpapers and themes > Themes (on the bottom) > then tap on "View all" at the top and select default. You should now be able to enable Night Mode.

Tap and hold on the calendar icon while on the home screen then tap on "App info" then tap on "Force stop" before going into "Storage" and tapping on "Clear Data".
