[/DeviceCMYK] is a way to selectively disable CIE based conversions
for the /DeviceCMYK color space. The user doesn't need this.

No. Specifying [ /DeviceCMYK ] leaves CMYK colors unchanged.
The CMYK colors will be printed later as device-dependent colors
or displayed as simulated printed ink colors in case of Acrobat
Reader.

The user wants to simulate the effect of the standard PostScript
CMYK to RGB conversion as it looks on the screen in device-independent
way to get the old colors in Acrobat Reader window and (as far as
possible) on the printer. That's what does the proposed color space.

I agree with /TrivialCMYK.

from other rants.
