Curvature baking ,not getting the same result between displacement map and mesh

[animk]

I am baking curvature on a displacement map.  The curvature baking on displacement map(top) looks very bright.  Did I do anything wrong?

The bottom one is curvature baking on the mesh.

Which blend type are you using ?

The curvature map is on standard blend, the displacement map is also on standard blend. 

Baking per pixel painting w/ normal map makes the normal map on normal map blend, and the curvature works fine.

But baking microvertex makes the displacement map on standard blend, and the curvature map is off.
