Gimp uses only one internal colorspace, 8bit RGB and I don't see that changing any time soon. So, you will never make operations in CMYK. The whole point with colorspaces is to have acurate colors. If you work in a colorspace with a wide enough gamut you are ok. That's why photoshop uses internally Adobe RGB 1998 independently of the images original color space.
