You are exactly right - the greatest contrast on a monitor - a "transparent"
media - Is viewed in a darkroom. And you are correct, that a reflective
print or proof shows maximum range in a very brightly lit room.
I used to work for a photographer, back in the days of film. He would shoot
spectacular 8x10 transparencies, put them in a black matte (usually choosing
a bracketed transparency that was about 1-stop darker than most of us would
choose) and then place the transparency on a light box with all the lights
in the room turned off. The Art Directors oohed and aahed about the
contrast, color saturation, and praised him for achieving what no one else
could. Of course, no one could print these dark, contrasty transparencies,
but the photographer claimed he produced photos, not printing, and it wasn't
his problem.
For a while, Sinar AG, camera manufacturer, promoted a theory called "Four
Stop Photography", meaning that the darkest areas with detail and the
brightest areas with detail should not exceed four stops, as that is what
can be reliably reproduced on paper. It was controversial, but largely
accurate.

So, you're saying that in order to do the utmost critical observation on a
display, in order to fully appreciate the 'digital' dynamic range present in
an image, almost or very close to total darkness is practically the only
condition in which our eyes can fully perceive those very dark details. It's
interesting to note that on a print, it's quite the opposive,
physiologically: in order to help our visual system fully appreciate the
last ounce of detail in the shadows of a print we need lot's of
illumination, hence the ISO-3664 P1 of 2000 Lux level.
