They’ll probably let you blacken out the top to form a ‘bezel’, only it’ll be a smart bezel - one that contains status bar icons (are you listening, Google?), which means you get more screen below in possibly a smaller form factor than the current S9 series.
That’s for Portrait orientation.
But when you’re watching videos/gaming/taking photos in Landscape, you’ll have a full screen with a small pimple as the only thing not displaying anything. It should fade away as you’re distracted by the rest of the screen.
& in a few years, when phone manufacturers develop a treatment for that pimple
, there’ll be nothing to fret over.
Stepping stones.
