Jay, the image from a staining developer *could* be grainless, but it's unlikely the stain will ever be exactly the same density as a silver clump (and if it were, that area would print pure white, a "blocked" highlight). Rather, the density between silver grains acts (as has often been touted over the past century) to reduce the appearance of grain, because it reduces the intensity of the dark spots produced by light coming through the interstices.
