First of all, that you don't see a difference probably has two
reasons: You have to have PDF documents that contain overprint areas
and you need to have compiled Poppler using CMYK support.

What it does is to ask Poppler to try to simulate the subtractive
mixing of several layers of color on a printout (in contrast to the
additive mixing the your monitor does). [1] does contain a bit of an
explanation, but I don't know a French-language source off-hand.
