Curvature map is sort of restricted to the resolution of your hi-poly mesh. You can either subdivide your hi-poly more, or you can just increase sampling radius beyond the limit of slider. Try turning off Relative to bounding box and increasing sampling radius to 2.

Thanks a lot! You saved me.
Now the curvature map looks even better than I expected, thanks to sampling radius 2

Before the new baking session, I think the curvature map was generated through the normal maps. One way around is to change that. This generator based on mesh seems not to be reading the smoothing groups, it reads the raw face. Even if you have a smooth surface in your high mesh model it will look faceted.
