To me it seems to be a PvE specific emblem. You play the story to reach lvl 20 and unlock raid I believe. Beat the raid then beat it on Hard. You play Dark Below story to unlock raid. You play the raid then beat it on Hard. You play HoW story to unlock PoE. 100 crucible matches to finish an exotic bounty. It's basically playing to unlock everything in the game. Trials of Osiris is a special exclusion because unlike those other requirements Trials doesn't work with the weekly reset while everything else does. To me the emblem makes perfect sense. The golden chests just add to the Patrol experience which has daily events, bounties, swords of crota and prowling wolves. To say you got all the golden chest probably means you explored every area in Patrol and witnessed all the events that occur on each planet.
