The point here is that your PDF will be CMYK. If your images are RGB
they will have to be converted to CMYK during PDF export, using the
profile and rendering intent you have chosen.
The profile and the rendering intent are what decides how the RGB
black in a photo gets converted to a CMYK black.
Adjusting the RGB images in GIMP might not give you the expeced
result, if it is the profile and rendering intent that is the problem.
This is what color management is about, knowing how the printed result
will look. To get it to work you either have to make test prints or
make sure you have a fully color calibrated workflow.
