No, the energy capacity never changes, just the energy delivered.
Tesla could be rating them for a quasi-static discharge rate.
But what does it then matter to me that the battery is 85kWh when this is just theoretical? I mean if the car battery couldn't ever under any thinkable normal circumstances deliver more than 81kWH then, according to me, it's an 81kWh car battery (when used to drive a car). They shouldn't market them as 85kWh.
