Height map not applied as expected to blender asset

Hello

In Unity, let's consider a Material(Standard Shader) which has albedo, normal map, height map applied to it. If i create a 3D Cube and use the defined material above, I can clearly see that if has effect and it looks good. However, if I import an .fbx asset(let's say it's still a 3d cube), created in blender and apply the same material to it, it doesn't look that good. I've observed that when looking very closely to both objects (the one created in unity and the other in blender) and in the material inspector i change the height map's value there's a very very tiny difference in how the blender asset looks but a very noticeable difference in the unity object.

Any ideas what i'm doing wrong? Thanks a lot
