Oh, wow. I see what you mean now — how Filmic chooses different values for white and black relative exposures, irrespective of the exposure module setting for exposure compensation.
(I also happen to use an X-T2 and hadn’t noticed this before. Sorry for misunderstanding. 
I guess I hadn’t noticed this before, as I’m not using DR on my Fuji.)
It does seem like filmic probably should automatically adapt to exposure’s setting. I suppose this might be an oversight? I guess file a bug and/or we can ask @anon41087856 here if filmic should take the exposure compensation setting into account as well?
