Describe the issue

With MonitorControl set to "Use fine OSD scale for brightness and contrast", when pressing the Brightness keys, there seem to be only about 60 steps from backlight off to full brightness.

In fact, I am not counting the same number of steps each time, even when I turn off key repeat and automatic brightness in System Settings. There seem to be more steps on the way up than down. The OSD visibly moves more for some keypresses than others.

Expected behavior

MacOS lets me adjust the internal display's brightness smoothly and consistently from 0-64 by holding Option and Shift while pressing the Brightness Up/Down keys.

MonitorControl should alllow me to do this without holding any modifier keys. It should go from either 0-64 or 0-100 with the same size step each time. Going from 0-100 would (I assume) enable better brightness syncing with external monitors.

Anything else?
