I am not so sure, as this is all based on the Nikon D300 photon transfer curve, which for sure does not represent an ideal form of a sensor.

He is stating something of 14EV as an endpoint, which might result from 14bit AD-values, but take into account, that for a white level, you have 3 stimuli adding to the total value, not just one! So maybe, there is a value of ld(3) missing. Green is not white!

Also in display metrology, white is way brighter than one of the three primaries, which sum up to white, in the end.

Color matrix calculations always take into account all three primaries for the total integral flux, that's why color matrices are 3x3 matrices.
