Yes you must program the car (this process is called battery registration) when you replace it with a new battery. This is because the car's IBS progressively charges the battery less and less as capacity decreases with age. So if you do not register the new battery the car will under charge it and that will cause the battery to degrade and lose its peak capacity even faster.
How did you check this "total capacity" F87?

I didn't know that the car charges less as the battery age. Good to know. But since we usually charge it externally on our own (CTEK, Noco etc) anyways, it somewhat circumvents that.
