Only, there isn't a photometric value for it.

RGB, without embedded ICC profile, is mostly agreed upon to mean sRGB. 
Another and probably more unambigious way to store color data, even if I 
feel RGB is regarded sRGB by just about anyone, is CIE L*a*b*, and there's a 
proper photometric for that one and a totally unambigious scale and meaning 
for floating point CIE L*a*b* data.
