isTrueCurveClient property
True if the geodatabase is a sync-enabled replica created by requesting true curve geometries, false otherwise.
If ArcGISEnvironment.serviceCurveGeometryMode was a ServiceCurveGeometryMode.trueCurveClient when the sync-enabled geodatabase was created and the service supports curves, this value will be true.
When true, the geodatabase will be treated as a true curve client when synchronizing edits with the service.
