The settings give you two sliders: one for the TV peak brightness in nits and one for paper brightness.
I needed to look up my TV peak brightness from here

Then I had to fiddle with the paper slider before returning it to the 400 nits default.
Also there is the regular Brightness slider which in other HDR games is useless for HDR but now I had to turn it all the way down to actually lower the brightness.
I feel this whole thing is too technical for basically a brightness slider and other games have dealt with it much better. Those sliders should've been the advanced settings not the default ones.
