How to set default screen brightness?

[Cosmoglow]

Is there an option to revert back to the default screen brightness? I like to leave things at factory default settings and hate guessing where the slider bar goes. Is it factory set @ 75% with autobright turned on? I read online it was set @ 50% w/ autobright... Someone please tell me there is an option to set "default" brightness.

Dont know why this is so important for you but I know that the default is 50%.
