Surprisingly there are some big differences between blacks. the most common are blue/black and brown/black. Most people would never see it but it's there. On my mixing computer at work it shows 7 different tints going into Vivid black. Not much of some, like a couple grams of white, yellow. blue and red each into 400 grams of one of the black tints. We actually have 4 black tints alone on our system.
