Comment (by robe):

 No.  I think the <<->> in 9.5+ returns tru distance rather than centroid
 box distance.
 Though I see our docs don't mention it which they should:

 http://postgis.net/docs/manual-2.2/geometry_distance_centroid_nd.html

 All the old centroid box KNN operators use recheck in 9.5+
