Wait...

Isn't the dot pitch specified for all dots (red, green, and blue)?

Consider a black-and-white picture displayed on a color monitor.  All
three dots (R, G, B) must be equally intensely lighted, yielding much
poorer resolution than obtained from the above calculation.

Possibly-irrelevant fact: Color television broadcasting separates out
the intensity from the hue.  The detail is mostly in the intensity.
