Hmm as far as I know there isnt any "empire morale" is it?
Yes and no. Civ-wide approval is not an ability, but was supposed to be (hence the Secret Police Center's description).
The approval bonus granted from having a planet at a PQ greater than 10 is approval rather than morale, but is planet-level only.
Technically all "morale" bonuses (racial bonuses from anomalies, customization points, techs, trade goods) are "civ-wide morale", whereas the improvements themselves (virtual reality center, et al) are planetary morale.
