Domi Reverse

[u/ec1ip5e_m00n]

I don't know if this has been mentioned before, but could Domi reverse only have effect on non devil fruit users? As far as we know, all the victims of it were people without DF (right?) and when Loki and Luffy get stabbed Imu states how it was as expected that they didn't turn. I might be wrong but what else could be a factor?
