Incompatible Spatial References

In the Pro SDK API, I am getting the "Incompatible spatial references" error when performing Geometry Engine operations like Distance or Difference on two geometries. The first geometry comes from a feature in an enterprise geodatabase feature class contained in a feature dataset. The second feature comes from a file geodatabase feature class created programmatically, with the spatial reference copied from the SDE feature class. When I look at spatial references of both geometry objects in debug mode, they have identical WKT strings. The workaround I found was to convert both geometries to JSON and re-create them from the JSON strings. The Geometry Engine operations no longer fail.  

My understanding is that as long as spatial reference WKT strings for two geometries are identical, their spatial references are the same. Is there something I am missing? Could this possibly be a bug? 

I am using Pro 2.6 SDK. Thanks.
