Once again, about the IFE system on the modded aircraft, is the large bulkhead monitor for the safety video in both cabins, or only in BusinessElite?

I understand the rationale of putting one in BusinessElite (as the PTVs must be stowed during takeoff and landing), however, if the bulkhead rows in Y have the PTVs mounted on the bulkhead wall then there is no need for any additional monitors which would otherwise be useless weight.
