Is it possible to reset to default screen brightness after manually adjusting brightness on macOS (with auto brightness adjusting enabled)?

After making a manual adjustment, It seems my mac's auto brightness is not working as it used to do. When I turn off lights in the room, screen brightness goes down but still too bright than it used to be. I need to get the default behavior back. Please help!
 
This is one of the strange limitations I can't understand after switching from Windows. It seems it is not feasible as such. macOS has this learning behavior just like some Android phones, that even if auto brightness is enabled it will learn your behavior patterns (like more or less brightness) and it will set it next time under similar lightning conditions. The point is if you by mistake do too many adjustments it gets crazy, but of course nobody thought about an option to reset it to original settings just like on Android phones where you can reset behavior patterns with click of a button.
 
I'll be very surprised if the Mac does this. It makes no sense to keep the display brighter than usual if the ambient light sensor detects little visibility in the room.

It makes perfect sense as everybody is different and you can adjust it for yourself. If I prefer brighter display in dark room MacOS ambient sensor will remember it and next time will use the previously used brightness. Check it for yourself, it's very easy. But this is not the point as the feature is quite neat. The point is how to reset learned behavior patterns.
 
I have suffered from this issue too, I know that creating another login account will put it back at defaults for that new account. There should be a preference file somewhere that stores this info, hopefully if we find out what the file is we can edit/restore it to default.

I can say this is still an issue all this years later lol. This is weird considering that you can do so on iOS. What gives?
 
I am not sure if this software helps in this case, but worth to try (there are many controls relate to brightness and backlight. Therefore, it may change the actual brightness curve, which affect the auto brightness behaviour). Free to use most functions anyway.

I will check it out, thanks!

It's in the High Sierra thread. If you have High Sierra that app doesn't work. That app only works from Big Sur up
