Yes, it's the PA kicking in; here's a small study I did earlier this year:

Other than the bump at the PA transition, the power increase per output watt
seems pretty linear.

The interesting implications come when running from an energy-limited
source like batteries:  how much power cost (operating time penalty)
do you want to pay per dB increase in signal?
