COBE and the Planke Explorer were/are designed to map the CMB which is effectively, the temperature of the 'universe'. Is this a correct statement?

if the statement is correct, then aren't they just taking the temperature of whatever is 'seen'? Now we are supposedly surrounded by a large volume of dark matter. Matter, must be warmer than its surrounding space, even if it is very cold, so might these CMB pictures be showing the location of Dark Matter?

(just been watching Stephen Hawkings Universe again)
