There are many differences of course - human vision applies
a whole lot of processing beyond the raw color signals to
ultimately make what we see useful to us.
I'm not familiar with this technology and is hard to understand, for
It's not "technology", it's the fundamentals of understanding
human color perception.
me, that monochromatic laser light source don't overload the sensor no
matter what filter is previous to photosites.
All sensors have light range limits, but silicon based ones
followed by A/D converters in particular have hard limits.
But typically there are ways of setting the overall sensitivity,
by adjusting integration time and/or apature.
Agree. But you say practical gamut limit. I supose that you mean gamut
limit of a display because you refer white point.
Most popular interchange formats use an output referred colorspace.
Once again though, the gamut limits are imposed by the
per signal value limit. If you expand those limits (ie. scRGB etc.),
the gamut limits are released as well.
Cameras have many limitations, but gamut is not one of them.

Jack's paper is about the limits in accuracy posed by the degree
of metameric match to human vision. His use of the term "gamut" in
this context is controversial amongst color scientists.
