What is the economic effect of the extractor trick at 14 supply in Legacy of the Void?

The extractor trick is used to temporarily build units over the standard supply cap by morphing a drone into an extractor, building an additional unit, and then canceling the extractor. This costs six minerals and lost mining time for the drone that morphs, but it gives a slight initial advantage in worker and larva count.

In the standard 13 drone/13 overlord/ 14 drone start to a build order, the player will be supply blocked while waiting for the overlord to hatch. This raises the question: is the extractor trick worthwhile? What is the effect on minerals, workers, and larva from a 14 supply extractor trick?

This is a subject that has been covered before Legacy of the Void, but the 12 drone starting count could fundamentally change the results, and I can't find any breakdowns in other places. I am specifically interested in the trick's effect on a macro-orientated 16 hatch/16 pool/16 gas build order, but answers that have a broader scope would be welcome too.
