These settings work for me.
Made them myself through lots of testing. Everything seemed dim to me so these settings require less light to make the screen brighter, and there are many levels to compensate light in different settings. I'm also using a pretty dark theme, so I can attest to this working well with darker themes.
I have light sensor filter enabled
Window lenght 2s
Reset threshold 400 lux
Sample interval 1s (which I think is default)
Use custom enabled
Screen dim level 20 (default)
Edit other levels (see pictures)
Allow light decrease enabled
Decrease hysteria 50% (default I think)
Main stuff that matters is the filter settings, 2 second window means it only takes 2 seconds for your phone to react to a change in light, reset threshold 400 lux means if something flashes quickly in front of your phone it wont throw off light adjustment.
