Many apologies for this, on further poking it turned out to be a
"problem between desk and chair" (user error). I misread the /etc/
powerd/powerd.conf comments and thought config_IDLE_DIM_LEVEL was
represented as a percentage brightness (0-100), but it is actually
based on the 0-15 hardware levels available. It was originally set at
5, and in an attempt to reduce the dimming up/down behaviour, I'd set
it to 50 (15 or above is no dimming), and then later assumed it was a
percentage.
Regarding dimming: I think it's less that the current dimming settings
that distracts me, but the apparent random wake-ups – I'm assume it is
network, or intermittent background activity that wakes things up.
I'll try reducing the config_CPU_IDLE_LIMIT and see if that helps
prevent seemingly random wake-ups.
Apologies,
