Was the Nikon D750 from the Period of Peak Camera?

Back in 2014, we reviewed the Nikon D750. That camera boasted a 24MP full frame sensor. And in so many different ways, it was an incredible camera. It also made us realize that if companies are still using 24MP camera sensors, then this might've just been the era of peak camera sensor. So was the Nikon D750 the start of the peak camera? Well, at least in terms of the sensor, we'd probably say so.
