I guess it's not the meters, which are doing their job to get the correct exposures, but the way the ISO scale has been calibrated, which in turn forces the meter choose to 2/3rd stop longer exposures. Would suggest that the 5D3 sensitivity extends 1.33 stops higher than the D800, not the 2 stops indicated by Canon. Equalized to the same relative sensitivity then, they are about 25600 vs 68000, or something like that, not factoring in the relative quality at those settings.
