My old S5 still has a great display and kickass battery life (original battery). Not quite as nice as my S7 display, but nice nonetheless. Anecdotes... amirite?

I imagine the panels Apple gets from Sammy will be calibrated very similarly to the panels that have earned Displaymate's best display for a number of years running. Hopefully they will also have the ability to choose display modes as well. One of the best features of Samsung displays.
I truly believe you. It may not have been what you meant, but it's
exactly what you wrote. Unlike my clairvoyant wife, I can't discern the intent written between the lines. Neither can she, but I am not dumb enough to dissuade her of that belief.
