Does Deadshot Daiquiri Tighten The Spread On Shotguns?

I know Deadshot adjusts your auto-aim, tightens your hipfire spread, and eliminates sway on sniper rifles, but I was wondering if the change to hipfire spread also effects a shotgun's pellet spread. I was playing Olympia-only Shangri-La earlier and picked up Deadshot for lack of a fitting fourth slot perk, only to find that more of my pellets seemed to be landing on what was directly infront of me instead of the edges of the screen like is usual for the Hades. I'm not sure if it's confirmation bias or if there's something to this that people just don't talk about because Shotguns in zombies are ass.
