TPO is the same color on both sides, and EDPM is black on the back side and white or whatever color on the outside.
You can access the back side of the roof material at a vent fan. Remove the four screws that retain the trim and remove it, and you should find where the roofing material was cut in an X and folded down and stapled.
Call Dicor about the use of the coating on the different materials. I am in the process of re-roofing a Thor/Dutchman Freedom Spirit that leaked at the TV antenna. The antenna found its way to the trash. I haven't ordered materials yet to install, still trying to decide, but I am just about through with the wood sheathing replacement.
