Can you try adding this line:
Option RegistryDwords EnableBrightnessControl=1
to your /etc/X11/xorg.conf at the bottom of the device section? It's not
something we can globally enable but it does fix many issues similar to
this.

I could read on the internet, that sony is using an unconventional way
for backlight support, it is using directly the nvidia chip to do so...
I hope this can help...

Upstream, the kernel team is saying that it is a platform driver issue
or bios... sony is not supporting linux, so I think the only way to have
it fix before 2050 is to bring the nvidia driver to manage backlight
(also in /sys and /proc) so adding nvidia pkg to the report...
