Acredito que a única forma de calibrar de fato qualquer monitor seja utilizando um espectrofotômetro.
Só se for um espectrofotômetro industrial/científico...
Espectrofotômetro comum(i1Photo Pro 2/ColorMunki Photo) não consegue ler adequadamente
os tons mais escuros dos monitores como um colorímetro(i1 DisplayPro/ColorMunki Display).

considered to be more accurate than colorimeters. (They are also more expensive.)
However, there is a major drawback. Because they read more bands of light, they will tend
to introduce more noise into the mix. This is not much of a problem until you get down to
measuring things like shadow detail and blacks. Imagine you're a spectrophotometer, dangling
off the front of a display and you're asked to measure a black patch. Well, there won't be
much of anything there to read, but you give it your best. You gather all the data from some
36 bands of wavelengths and because of digital noise and sensor dust, that will add to your
report of how bright black is. For this reason, spectrophotometers tend to not measure shadow
detail as dark as most colorimeters do. For example, the Monaco Optix (DTP-94) is famous for
getting great shadow detail. It even has some noise-reduction circuitry built into it."
