Describe the bug

When I change the brightness of the monitor with the keyboard keys, the dimming is not displayed. See the attached video. It's not visible but I change the brightness of my monitor. Compare with the change in volume, there is a gradation, but with the change in brightness, it is absent.

Steps to reproduce

Press de the keys F1 and F2 on the Keyboard to change de monitor brightness.

Expected behavior

We should see the gradation on the native MacOS preview.

Anything else?
