the problem still exists, I try this option before I start to write a post on this forum, this is the first time when I have a problem with the renderer, [I used Vray, Fstorm, MentalRay, Corona, Blender renderer, Maxwell, no problems with EXR]

do you have any idea how to save correctly ...

I and you missed this, you can't compare float(tonemapped) vs. exr saved from LV ...
