No, the sum of DAC and ADC could be both additive or compensating on certain frequencies. The point is YOU don’t know, WHAT is causing the depth. 1 person could have the match in heaven, but the worst result because he has a fridge humming on the same power group. Who knows? That’s why this test is completely useless.

Moreover, if a pair in Didier's list produces a file that when subtracted from the original produces a result with a 70 dB RMS difference, I would confidently state that both the DAC and ADC in that pair are excellent individual components (at least in terms transparency) and I defy you to state otherwise.

Let me guess.... you own some equipment that is included in Didier's list that isn't ranked very highly.
