Seems that your title as leader of the very institute didn't bring anything except a few new idle lines from Institute NPCs, except they had so few extra lines of dialogue they never stopped mentioning Libertalia. No new quests for spreading Institute control over the Commonwealth (although I really appreciated that they added Synth patrols that will secure pre-war military checkpoints, really nice touch.
I was utterly disappointed upon realization that the only thing I got from becoming the Director was a new quarter, you already had one, a power armor paint job, and a lab coat. I couldn't wait to unleash the power of the Institute. So I recently finished my first main quest playthrough of FO4, I sided with the Institute of course. The most advanced technology the Commonwealth has ever witnessed is in your very own hands. So you've inherited the position of the Director of the Institute.
