take into account the difference in reflectance of the digital sensor (and it's smaller size), compared to film. It should
by all rights be more consistent, since the reflectance never changes, but apparently is not.

I understand it like this: An auto flash will have its own built-in quench circuit. As long as you follow the ISO/aperture/distance guide, you're okay.
TTL relies on the camera to quench the flash, and if the camera can't get it
right, then...
... the camera is defective and needs servicing ?
If auto flash is able to get correct exposure why wouldn't the camera be able to do the same thing. TTL flash should work better than auto flash not worse.
