If you want to work in AdobeRGB, set this as the workspace profile in 
digikam's settings. The color management settings for RAW import are somewhat 
separate, easiest is that you set the output profile to Adobe RGB as well.
If you specify "no" input profile, libraw will do its best to get the colors.
For the perfect result, you'd need an input profile specific to your camera.

You need to look at the color tab in the right sidebar

Yes. In the editor, you can switch it on and off and see that the colors will 
be slightly desaturated without it. It's much more obvious with wide-gamut 
profiles. The output is simply wrong.
Isn't color-managed view enabled by default?
(again, for the perfect result, you'd need an output profile specific for your 
screen. If you dont have the necessary hardware device, or a cheap notebook 
LCD, then sRGB should be good enough. I'm using sRGB here as well)
