The numbers that are changing between the two displays - pace, power, and stroke rate - are all instantaneous measurements, meaning that they normally would represent a single point in time during your workout. They can be applied to your whole workout only by averaging them over the duration of the workout.
So you had an average pace of 2:14/500m over your workout, and the maximum speed that you hit was a pace of 1:57/500m. Your average power was 142 watt, and the power you were putting out during your most powerful stroke was 216 watt. Your average stroke rate was 32 strokes per minute, but at the fastest point in the workout you were pulling at 41 strokes per minute.
You burned an estimated 1094 kcal during the workout, but I have no idea what the 2714 value in place of this on the max screen is.
These numbers suggest that you were working at quite a consistent intensity. Whereas if you had been doing an interval training workout, where you alternate periods of unsustainably high intensity exertion with periods of rest, then you would expect to see much bigger differences between the average and max values.
