What is the background density of dark matter?

[BillSaltLake]

Far from any superclusters, is there a background of DM which hasn't yet clumped (at least to any great extent)? What is its density compared to the average DM density (which I think averages about 1 GeV/m3 in the present)?

DM is rather unvenly distributed through the universe in fliaments. The density outside these filaments could be considerably lower. See

Would there be any ΛCDM theoretical papers that give predictions on the DM distribution in the form of a graph, such as X= percent; Y= fraction of DM lying within the densest X percent of space?
