Can you make screenshots of what you mean ?
Makes it easier to assist.
(Ps, i would not leave your email address behind in a public forum , but that’s me ).
Output profile in the ‘output module’ is set per file , so every file has a setting. It defaults to sRGB , which for output seems reasonable .
In the export you can override this if you don’t want to bother with setting it.
‘input profile’ seems highly unlikely that it’s set to sRGB , this is normally set to ‘standard matrix’ or something similar. This is the 'camera profile ’ so to speak. No camera has sRGB as input profile I’m guessing 
.
If you want to use your own camera profile , it needs to be ICC and not DCP and needs to be placed in color/in (the directory other people gave you . $HOME is also valid with macos I’m guessing , but it’s for in the terminal. It’s your home folder . The ‘.config’ should be there but might be hidden (that is what the dot in front signals ).
Using dcp profiles for other software packages in Darktable is not straight forward.
