We DO know that the entire universe only contains 4*10^69 J in mass-energy. How do we know this? Because this was the amount of energy contained within the explosion of the big bang.
Another way to calculate this and come to the same conclusion (proof it's correct) is to take the average mass-energy per cubic meter of space in the universe and then multiply it by the volume of the observable universe. You'll come really close to this number.
In the end it doesn't matter what classification the mass has because it's all mass-energy no matter what shape it takes. Photon? Mass-energy. gravity? Mass-energy. Your mom's fat ass? Mass-energy.
It's all Mass-energy so 85% of it not being properly classified within it doesn't matter since we know its main classification and the rough estimation of its location.
