I reserve this diamond , I color:

I was browsing Rockytalky, then I saw this K:
http://www.zoara.com/diamonds/p_round_excellent_cut_k_vs2#p=1594413

It looks to me that the K appears whiter than the I. Can someone please explain this to me?
Also, is the I color diamond an ok choice or can I do better?
FYI: my budget is upward to 7k, but I'd like to stay in 5k range, down to J color if necessary to have a bigger bling
