Does not match library/development with export

[luca.gerla]

Good thing this is my problem

To the left the photo develops to the right as I see it on lightroom

My problem is the visualization of photos in library and development does not match the developed photo or the developed photo becomes clearer / overexposed. I tried with other software Nikon and the match is perfect, so it must be a Lightroom problem.
I have a nikon d750 and I have a Lightroom 2015.12 license
Thank you for your answers

For me no answer is it a problem that can not be solved? Sin was hoping for a solution
