I first noticed that the screen was very different on iPhone 7 and i would return anything in a second if not satisfied. I just came back from apple store and i spent 35 mins comparing side by side a 6S Plus & iPhone 7 Plus. Went to the store thinking i would return phone but after visiting sites like Macrumors,CNN,Drudgereport,Apple.com,ESPN etc. and just doing a side by side comparison i have to admit that iPhone 7 is a far better screen than the blue hue screens. Colors seemed off on the 6S. This is when side by side displaying content and i am not talking about the settings screenshot. Just sharing my thoughts and of course each one will do as they please. Try it before you just return it. just a thought.
