Since the last patch (EotM), all the World Bonuses gained from WvW do not seem to apply to the game world (at least, the two obvious ones, +max health and +healing, in dungeons and open world PvE of your world). I’m not sure if this was intentional or a result of a bug from the last patch. I didn’t see this mentioned in the patch notes so perhaps this is a bug?
