Automatic Brightness Lag

Hello all,
I'm running xiaomi.eu 8.1.6.0 stable (clean flash) and I'm having a problem with automatic brightness. The brightness gets stuck on too high when ambient light goes down or stays too low when ambient light goes up.
I tested this right now in *#*#MIUI#*#* menu and the behaviour is as follows:

DAC --> Backlight level
1 lux --> 3
500 lux --> 54
1 lux --> 27
500 lux --> 56
1 lux --> 14
(do lock/unlock)
1 lux --> 3

As you can see, the backlight level does not get down to 3 unless I cycle it more times. First I thought it's just lag, but it doesn't change even after 30 seconds.

Does anyone know what's going on and how to fix it? What is the algorithm for changing brightness? Is there a way how to change the behaviour? It's really annoying.
I do not want to flash a developer rom or Nougat, so please do not recommend that. Thanks for any info.
