I never noticed until I read this but comparing IE and Chrome side by side it is obvious.
There is color difference as well when using IE 9. However, it is minor compared to Chrome. Wow.
I, however, worry more about seeing/working on color in post processing of my photos. I sometime deliver a photo that looks good on my laptop, but looks less good on someone elses laptop. That worries me. I want to make sure that my post processing is coming out in a way that it looks good on other screens as well. Don't know how to manage that......
