Clevo backlight

So, it seems I never gave a status update on the reverse engineering of the backlight.
I basically hit a wall. The EC is readable and gives status on the current backlight level.
Unfortunately it seems that writing to the EC accomplish nothing. I currently suspect that the windows backlight driver doesn't write at all but only poll relevant registers in the EC and show some graphics upon detecting a change. If someone has an update or solution to this, contact me ASAP.

How do you read the level? I have the M570TU model and want to solve this issue too.
