Immersive mode as implemented by Samsung on Note 20 Ultra is crippled, doesn't span the display area over the full display, only hides the status bar. The effective visibility area for apps is without the top bar around the camera cutout.
To enable full immersive mode:
— install Magisk module “None Display Cutout”;
— reboot:
— System Settings ⇨ Developer options ⇨ Simulate display with cutout ⇨ No display cutout - MlgmXyysd
Now the display area will use the full screen and be significantly bigger.
