iPhone 5S Display Color Problems?

[D.Somerset]

I've recently upgraded from a 4S to a 5s.

Not sure what it is, but the colors on my iPhone 5S screen look really 'hot', almost like someone has fiddled with contrast rather than brightness. I noticed this from looking at the title card of the Simpsons: Tapped Out game. Homer appears in his normal yellow on my 4S, but on my new 5S, he's a more dirty fluro yellow color.

Been playing around with screen brightness but this doesn't appear to have any effect.

Has anyone else noticed this with their 5S?

Hope this is not a problem with my phone and is just how the new displays portray colors...

I've also experienced this, not with a 5s but I've seen differences between iPhone 4 to another, our 4S's also had differences.
Over time though things seem to have gotten better, usually they say to just give it time and it should get better.
If you feel it's really bad then maybe you should go to apple and have it replaced.
In my opinion though, give it time
