 I reached precisely the same conclusion!  
 
What etchant do you use?
@ motan
The lighter patches are not the result of cleaning. They are intrinsic to the wootz, most probably the result of heat treatment different for the tip/edge and for the area near the hilt. I polished a couple of blades to mirror polish and etched them anew and got the same patches like before.
