It seems that to make brightness control work (with preferences slider and keys) is to use an AppleBacklight.kext injector (or patching the kext itself)
How can I edit the 4x40s plist to make it fit my display and newer hardware (like skylake)?
Is the only thing I should do is edit the plist file and create an injector, or I also need an ACPI patch (or another SSDT)?
The PWMMax value is determined by the data associated with your ig-platform-id. Look in the kext binary for these values.
Once you determine the PWMMax value, you can look for "example" data in native AppleBacklight Info.plist.
That will also help you configure SSDT-PNLF.dsl and SSDT-Config.dsl to set PWMMax correctly at boot (see my ACPI hotpatch guide/repo).
