At ISO 1600 the K 5 performs like any other modern APS-C in the whole range

That's not very accurate. It produces a similar SNR across the ranges covered by other APS-C cameras, but the the dynamic range at 1600 is at least 2 stops better than competing APS-C cameras.

If you look at the plots, at ISO1600 the DR of the K5 is not higher than 7D's DR, and is lower than 5D2's DR. The high DR performance is just for low ISO values. Just look at the SNR plots, nothing else is needed.
