PHOTOSHOP GRADIENT AND THE EXPROTING AS

What is the reason that the displayed gradient in the file, is different from how it is saved and displayed after saving?

Am I missing something? I jumped to a new version of photoshop yesterday and I'm not happy with how the gradient tool works ( Now I remembered why I didn't use the latest versions for several years )

I find it terribly hard to work on the new updates. They do not in any way speed up or make my work easier but actually complicate it.
