It is in every packet of this batch number we've been through thus far. It wasn't obvious in the dry powder, just that it was darker than usual, but on inspection the mixed developer had black particles at different levels.
I found no base fog, contrast, density, grain or sharpness differences after the black stuff was filtered out vs 'normal' ID-11 and D-76.
Inspection was made on a loupe and light table, densitometer, and also flextight scans.
I have not tried processing with it unfiltered (nor do I plan to try to).
