I'm with Thanh, when it comes to the actual behaviour of the program.

I do not see how pdftex could distinguish between a user who is
knowledgeable and purposely trying to achieve a special effect
and a user who is naively doing something redundant. In the case
of CMYK image files, the probability of dealing with an expert user
is pretty high, so the current action seems fine to me.

That said, the behaviour should be documented, and perhaps even a
warning could be issued if the /Decode in the image does not agree
with the PDF default value?

Best,
Taco
