Generalizations like that typically don't make sense, and yours is no
exception. I built my house on a hillside and had to backfill against a
six foot high retaining wall with hundreds of cubic yards of dirt that
dirt that I excavated from the same undisturbed hillside. I compacted
the soil against the retaining wall in lifts of a few inches at a time
using a 20 inch wide motorized plate compactor, with a sledge hammer to
compact in the tight spots. I estimate that the material I compacted
was at least 30% more densely compacted that any of the soil I dug out
for backfill (rocks excluded).

You'll never get the soil back to natural compaction.
