This projector seems quite a light canon, well at least as powerful as mine (Pro UB). Indeed for anything smaller than 115" screen I would not go DW. Too bright and blacks will be raised quite a bit and I would not chose Wilsonart Fashion gray for anything bigger than 100" as well.
This being said, Mech and Bill are better placed to talk about any colour shift, also Bill has the same projector.
I kinda feel I have complicated your life
...Just have Bill's opinion and make your decision.
