Is this information (delay between digital and analog screen refreshes)
included in the verbose output?
If not, could you please make it so? I think it worths a try to test (on
displays with already known refresh delay) how accurate it may be.

Taking pictures of the displays with running clocks is also far from
accurate because the sampling rate is limited to the screen refresh rate,
so you don't even have a chance to spot a delay lower than the screen
refresh period (and you always get a value rounded to an even multiple of
the refresh period...).
