Generally, no. The output stage is configured as either 1/2-bridge or full bridge depending on the power supply and the design of the power amp. 

 

I would imagine a bridge mode class-d that had the  outputs fully synchronised would be better able to see the advantage?

It doesn't even need to be synchronized for the benefit of increased power efficiency (though it may be necessary for other reasons such as EMC control, THD reduction or purely functionality depending on how the topology is achieved.) The PWM frequency is high enough that it all averages out with the lower audio frequency and the reactive power reclamation still works.
