Fine tuning display brightness : decrease minimal setting

Hello !
I am having a hard time with minimal brightness setting both on BL and vanilla Gnome Shell Debian 13.7 using their respective "slider" :

On BL the slider Power manager plugin only allows to go down to 750
On Debian+GS the slider only allows to go down to 75 (that is much lower than with BL, but still very high)

But I can echo 5 and get my display very dim without any flicker, 1 is too dark to be readable.  So it is safe to assume I can go down to 5, or maybe 15 as it is still very very readable.

is there any config file I can tinker with on any/both systems?

thank you !!
