I was just screwing around with this and found out something interesting.

In /etc/modprobe.d/samsung-backlight.conf you'll likely see;

blacklist samsung-laptop
options samsung-backlight use_sabi=0 levels=8 force=1

Remove the blacklist and keyboard backlight controls will work and org.freedesktop.UPower.KbdBacklight exists allowing you to control the keyboard brightness.

But the screen backlight stops working...

Add the blacklist back, screen brightness works again, keyboard brightness does not, and org.freedesktop.UPower.KbdBacklight does not exist.

I don't really have any more time to play around but thought I would share.
