LOW BRIGHTNESS → DIM AMBIENT WATCHFACE
I noticed I was setting these two at the same time, so there is now an option: 

The brightness bar allows you to set the display darker than the system “1” setting. If you set it to “1” or lower (on the Huawei watch it’s about half way on the seekbar!) the ambient watchface will also be automatically dimmed.

On the HW I tried to match these two: the ambient screen now appears to have the same brightness as the regular display.

BE CAREFUL
The lowest setting makes both of these barely visible: they are ideal for complete darkness. If you find yourself “locked out” of your watch, just triple-press the hardware button for the standard “Brightness boost”.
