I think I have a rough idea what the issue might be:
When I look into "/sys/class/backlight", there are acutally two subdirectories/configurations here:
The first one is "rpi_backlight/" where "brightness" is set to 63.
The second one is "10-0045/" where "brightness" is set to 255.
Interestingly the "echo xx > brightness" command works in both subdirectories and changes screen brightness to the respective value.
The setting in "10-0045/" is the one the screen returns to after screen blank.
