Why, why, why did I read all five pages of this?
Hit-or-miss like any other label, indeed.
The aesthetic vis-a-vis Af-Am musicians is interesting to contemplate, chalk it up to a lack of interest in putting out much music from a blues perspective (with exceptions like AEC, Redman/Old and New Dreams, etc).
European sensibilities also drove FMP, Incus & Enja (tho theirs certainly encompassed Black music - Waldron, Cecil, Dollar), and you wouldn't fault these labels for not having enough black music in their catalogues.
