I would like to thank you for the detailed explanation of your issue and also for the screenshots provided.
My recommendation would be to contact directly your OEM, the graphics control panel does have an option to increase or decrease the brightness but depending on how the applications interact with the device, the brightness could increase. For that reason it would be better to contact them and see if there is a remaining options to change for this to be better.
Also, have you checked if the software that is affecting you has brightness options in it? That could also help you with this.
