Spitballing here, but I had a similar problem with an older Dell. I found an adaptive screen backlight setting hidden in the BIOS setup, but I don't recall what they named it. Evidently this was some hardware bullshit and fiddling with screen brightness settings in the OS didn't impact it in way whatsoever. Disabling it in the BIOS cured it of being annoying.
