Well, I suppose, if they auto-correct your pre-layouted pages, things
might get pretty worse because there are multiple images in it (not so
with ordinary photos) and you've got a lot of black there. The images
might get very distorted.

Which kind of ICC profile do they provide? CMYK, RGB? You should use
that in any case to do the RGB->PDF export. You don't need a calibrated
system for that. You should NOT try to export to "Printer" (=CMYK) PDF
without color management activated! The results will be very bad.

You should check carefully in which format you deliver your photos -
CMYK is probably not the best option if you're trying to pretent to
deliver original photos - these are in RGB. Unfortunately, I don't speak
French, so I cannot check their page.
