So, from the arguments presented, anything that "breaks" the incoming spectra
into small bins is bound to receive "less photons", in all, in each bin?
Whereas colorimeters are usually designed with "large collecting areas", which
allow them to collect "more'" photons ", more rapidly or, at least, to collect
whatever available photons more rapidly?

I would not choose to use the term “less reliable,” but I think I understand
what they are trying to say.
Spectrophotometers like the i1Pro measure all bands of human perception at 10
nm increments. Colorimeters measure 3 colors. This measuring of 36 bands
instead of 3 is what’s blamed for the i1Pro not being able to measure as black
as a quality colorimeter. There’s just more noise in attempting to measure
light on a dark display. Every little wisp of light gets picked up by the
spectro. This is one reason why the basICColor DISCUS was valid as an
instrument for monitor profiling. At over $1000, it was a very good quality
colorimeter - but it was a true colorimeter, not a spectrophotometer.
