Your setup for backlight looks correct.
If it is not working, then it is likely your laptop does not use the IGPU PWM registers to control the screen backlight.
Therefore it is not compatible with AppleBacklight.kext.
I previously tried the other two methods, using ACPIBacklight.kext and IntelBacklight.kext, making sure to re-patch the DSDT with the appropriate patch with each one (regular "Brightness Fix" and "Brightness Fix (Haswell/Broadwell)), and they also did not work. They did make the screen slightly brighter by default, however.
Note: Your files in ACPI/origin are too old to compare against ACPI/patched (you forgot to press F4 as per "Problem Reporting").
How would they ever change? Wouldn't a previous F4 extraction vs. a new one pull the exact same stuff from the hardware, since I never changed anything in the BIOS settings? I'll gladly do a new extraction if you think it would make a difference in your analysis, I just didn't think it would be possible for a new extraction to be any different, since I never changed anything in the BIOS settings since the previous extraction.
I attached a new problem report, this time with the most current DSDT/SSDT files extracted with Clover.
