I don't know if it  has an impact or not, but if I remember correctly, Bagginsbilll one day stated that on bump and trans maps, gamma should be set to 1.0, and they shouldn't have any filtering applied, to be sure that the datas of those "pictures" arrive without any modification.
And that's something I'm doing each time, now.
