How do I get "-selective-blur" work with images of any size?
How do I get the same effect with an image of size <800px and more, like (2600px)?
my command: -selective-blur 4x6+09%

my command: -selective-blur 4x6+09%

I suggest you don't supply both radius and sigma as in your case your sigma is bigger than your radius, thus the gaussian effect will be cut off before tapering significantly. It is generally best to use 0xsigma and let IM figure out the best radius size for the given sigma.
