By the time you hit 2e, no. But there absolutely 100% was a functional difference between what oD&D called a Referee and a Storyteller. A Storyteller did not share authority over the PCs with other random groups in a West Marches style game.Naw... There is absolutely no functional difference between what WW calls a ST vs what D&D calls a GM. Neither system has mechanics to give players or rules agency over the GM/ST rulings.
Things had changed. PbtA changes them differently but OSR GMs and Trad GMs are not the same thing.
