AS REPORTEDno primary record reached; this is what the reporting says

Is it true that density and specific gravity are physically different measurements?

Yes. Density measures mass per unit volume with physical units, whereas specific gravity is a dimensionless ratio comparing a substance's density to a standard reference material.
