Re: So...but the screens are not what Sony think they are
I take photographs and I'm a bit of a colour accuracy freak. I prefer Sony because their screens are not oversaturated and a bit cartoony like Samsung and Apple, which is what I expect from a manufacturer that cares about optics and photography. I know other people like something that looks like Velvia on steroids, but in my mind the nearer to the rendition of the old Kodak Pro the better.
My wife buys a lot of wool over the internet, and I keep telling her to rely on the colour rendition of her Sony, not her Samsung tablet. I have seen people have exactly similar problems with iPads.
