I'll take a stab at this. I do not know what true mass is but what the amount of mass compared to energy sounds like you want a ratio of energy to mass. Since you only wanted a ratio, the exact quanity of total energy or total mass in the universe is not important only the ratio of the two is.
From
E=mc^2
E/m=c^2
or
m/E=1/c^2
From Einsteins equation the ratio for E/m is always equal to c^2 for an object. If it is true for one object it is true for all objects in the universe. Therefore the ratio applies to the total energy/ total mass in the universe as well.
