No. There is a difference between decaying and decayed. Stuff that is in those "live sand" bags are still rotting away. Dry sand, in theory, only contains stuff that rotted fully. For example, animals die and continue to breakdown till there's only a skeleton. "Live sand" has a couple corpses in it, and dry sand only has skeletons.
Skeletons are inert, so they won't effect your tank.
So you can say that all the organic matter on there has completely decayed and nothing is left? I don't buy that. unless they somehow cook rinse then dry the sand before shipment...
Another thing you can do is grab a handful of sand, wet it. If it smells like dead fish or rot, then you need to cycle it.
But again, if you've already dropped a 20 pound bag in the qt, and didn't have an ammonia spike then don't worry about it.
