Yes is the simple answer. But then I mentioned this with the fireteam medalion too. I saw no noticable difference between engram drops with or without one. Everything from the damage numbers you see to the chances of getting loot are simply a placebo in this game. Eververse items seem to make chances worse not better as now it seems does Xur's loot. Even the fated engram is a lie. I thought mine had worked as I got the colony from it but then, upon completing 3 milestones and turning in an exotic engram from public events (no 3oC active) I got two more! My drop from the fated engram being something I didn't have looks like it was a simple RNG fluke!
