I know a breeder who breeds Chocolate Orpingtons and Chocolate Pekin/Cochin Bantams and she always has her incubator running at 36.7 and the humidity at 45 % throughout her complete incubation - she doesn't even increase after lockdown, and her hatches are over 95 percent and that has been into the thousands therefore I would not worry too much.
