If you want my opinion, I would say: Yes, the closer to the real hardware output the better. There are definitively irregular color steps and you should take this into account.
I own several MVS systems (with different board revisions), AES systems and CD systems - if there is interest, I would take photos of the test image from all of them.
It would be interesting how to measure these DAC resistor values, could it be done with a multimeter? Maybe we could find out values which come closer to the average
real system output, if we do our own measurements on our systems ... who knows how many systems and which systems the guys from MAME have measured to get their values?
Is there any source or additional information about that?
