Only one datapoint, but two days ago, DL AMS-MSP, bought chocolates at a non-duty free shop and carried on board with no questions, no issues, no special packaging.
Doesn't make sense that it would apply only to items purchased (like chocolates) at duty free and not to items purchased at other airport shops.
