Well with the display dimmed from sleep mode, I can‘t easily access the control center so I can‘t use the red flash light from the Watch, which I need as my wife and daughter sleep in the same room. So if I am looking for something in the middle of the night I would have to unlock the display first but then using the control center, the display goes to the „max brightness“ for the given environment which is way too bright when I then turn on the flash light. In theater mode I can manually increase brightness of the display and it stays at that setting even if I use the watch.

Sleep mode alone sadly doesn‘t do it for my use case
