I admit I have not seen one of these "smart" monitors in action. So it's
unknown to me the degree of adjustment they can modify the monitor luminance
with respect to ambient lighting. But it does not seem to me like a useful
feature. To me, monitor calibration should be done for a certain viewing
conditions and remain fixed from that point on. Usually, people are after a
viewing booth setup that matches their monitor in luminance. Once they found
it, I don't see why they would want a smart circuitry inside the monitor to
alter the screen luminance to reflect ambiant lighing changes.

See above.

The only "norm" I know with respect to ambient lighting in the graphic arts
or photography is ISO-3664.

Maybe the folks at basICcolor have a different idea?
