Build report with Filled Map visual color question

Hello

I  have been built a sales  by country report based on Filled Map visuals.  

In the data color property I set Diverging off and specify Max/Min color based on max /min values. But even if the sales between the coutnries are pretty huge (20 mln and 45 mln) I see those countries with the same color. I would expect that let me say Russia with 20 mln $ will be painted in a contrasting color less than  let  me say USA with 45 mln $

Is that possible at all?
