Speaking from a purely physical point of view, the light emitted from a light
source and the light reflected by an
opaque body is identical except for its
intensity (aka its energy) and the frequencies involved (the frequency spectrum of light is what gives us the perception of colors).
Photons are photons are photons, to put it in internet language. When light is reflected from an opaque body, some of its energy heats the body and some is reflected: the reflected part is the light that your eyes catch.
If you diminish the intensity of the light of a light source, you can reach the same intensity of light "usually reflected" by opaque objects: in case of a Samsung LCD computer monitor, it means to reduce its brightness to 21% and raise its contrast to maximum (remember, contrast is not brightness).
But yeah, the photons remain photons.
