On my old phone I wrote an app to write screen brightness values directly to the underlying Linux device. It bottomed out at either 3 or 5, which was still way below what the normal brightness slider allowed but it seems there’s a hardcoded non-zero lower limit.
Can that not be done with LCDs and OLEDs? Turn off the backlighting at least?

Whoever hardcoded that probably was a victim of the prank one time too often. 😔
