Sorry,
still do not understand why the same scene rendered in blender, and than exported and rendered with standalone give different results.
Exr use 16 bits but still infinity should be infinity or not?
I attach my scene. What should I do to get the sky white?

The DEPTH.exr file shows INF values as expected

Thanks Dade,
I have solved this issue. When you open this image with gimp it gives black color for INF values what was confusing. I've been trying to open this file with openEXR library but I made a mistake. I was not opening the original image but compressed. And this is what I have found. If I open exr image and save it using lossy compression like DWAB, all INF values are LOST!

The first time Sheldon met Penny she struggled opening the door to her apartment. Penny answered Sheldon's question about what was going on with some kind of excuse because she plugged the wrong key into her apartment's door lock. Sheldon asked Penny in a rather puzzled mood as just read a fancy terminal message: "This error should actually never occur."
Well, I'll never catch it why there are these silly options to save a file of EXR type anything but lossless.
This is one of these flaws beyond my horizon ....
