Doesn't work on Asus UW5606 despite accurate sensor readings

[ThatOneCalculator]

For some background, this is on the Asus UM5606 (ZenBook S 16 2024).
The brightness adjustment via the ambient light sensor on GNOME works perfectly. However, I looked into using clight as I want to use a standalone wayland compositor. I'm also able to adjust the brightness of the backlight manually. Furthermore, the output of busctl call org.clightd.clightd /org/clightd/clightd/Sensor/Als org.clightd.clightd.Sensor Capture "sis" "" 5 "" gives accurate readings. However, brightness does not adjust at all when using clight.

Going through the wizard, here's my output:

clight -w

Which is a bit strange, since it gets the ambient brightness level but constantly sets the backlight to "1.0000".

Running clight with no args just keeps the brightness at max too, and using clight-gui it seems that it's not getting any readings from the ambient light sensor.

Going through the wizard again, it seems to have the most problems with setting the backlight. I did this in an entirely dark room, so the reading of 0 is accurate, but it seems to want to make my brightness 100%. I started the test at 80% (manually set)
