If your AOD choice will not surfice because of fear of things like screen burn in, depending on your device and the presence of the required chip, you should be able to flash a ROM (with kernel) that supports tap to wake.
Otherwise, you can create a fullscreen scene that reacts to a tap and depending on your device, if need be also use something like Darker Pro to turn the brightness down to total blackout which is also reversed with the scene touch, or perhaps better, a wave over the proximity sensor.
I believe it was initially just a safety measure to prevent going too dark and there appears to have been different limitations for Android versions throughout the ages.
Separately, as screens have become brighter and as Joao recently tweaked the top end, I suspect there may be room to also tweak the bottom end down to lower than is currently allowed as would love to be able to get down to total blackout.
If it's useful, I still use Darker Pro which allows me to go right down to total blackout and can be controlled via intents in Tasker.
The recent Samsung phones seem to be pretty consistent until 25-30%, where the PWM behaviour changes (more aggressive flickering).
Try setting your brightness to 40-50%, switch off auto-brightness, and use a screen filter app (I like darker; see if that helps. Don’t turn on ‘extra dim’ - it seems to do something funky with PWM.
It’s interesting that the Flip3 doesn’t give you problems. As far as I can tell, its PWM behaves exactly the same as the S22.
Friendly reminder to include things like your device model, android version, root status, etc. when asking technology related questions as it usually defines what options are available to you.
Should your device have an AMOLED screen, you could consider a black blocking overlay scene, else, one of the dimming apps such as Darker Pro.
Darker darkens navigation bar as well. I'm still on Nougat though.
I use Darker Pro; it has a pause feature in the notification bar.
I don't have experience with an Iphone, but i do find my self adjusting the Brightness too often or not being satisfied with it, like in a dark room i find the lowest setting to high, so i downloaded an app Darker pro

I use Darker Pro, it includes a filter for the nav bar.
I've always prefered Darker Pro
