I don’t know that pictures look ‘stunningly better’ compared to 3 to 4 years ago ( And Yes, I have used every iPhone), where iPhone 6 pictures that look still amazing for that time frame during 2014 when it launched. For the record, There are even comparisons out where the average consumer can’t even tell the difference between an iPhone 6 photo and an iPhone X, but that would depend on the individual experience and understanding of Camera tech. I think smart phone cameras have progressively improved year after year, but I don’t know if it’s ‘stunningly better’ in the respect that Camera tech is not that drastic in Camera advances, aside from features like Portrait mode/Portrait Lighting, etc.
Now, if you want to compare camera technology I would say 5/6 years ago compared to a BlackBerry compared to the iPhone, that would be stunningly better in today’s applications and more of an appropriate example.
I agree in regards camera, funny enough I saw this a few days ago, made me think.....
