Yes, for PDF/A and PDF/X output.

pdfwrite doesn't know what colour space the colours are defined in, in the 
input file. Although you have specified -dUseCIEColor so that colours are 
transformed into CIEBased colour spaces pdfwrite has no way to know this. 
Also if the input was a PostScript file this switch could be turned off 
again, meaning that colours might then be encountered in a device-dependent 
space.

PDF/A specifies permissible device-dependent colour spaces, and you may 
only use one of them in a given file. pdfwrite requires that you specify 
which colour space you will use, so that if it should encounter a colour in 
a device-dependent colour space it will know what to do with it.
