Fake or just old?? Diptyque - Orphéon

Hey folks. The packaging on the left is from eBay and the right is from Jomashop for comparison.

Ebay version does not smell like Orphéon, and the packaging is different/lower quality from the Jomashop version. The seller claims that both of these issues are because the product they’re selling is 4 years old and the packaging and apparent quality of the perfume has changed since then. They swear it’s authentic.

I’ve had some of my luxury perfumes for 7+ years and have not had the liquid diminish in quality as badly as the eBay version has so that’s another reason I think it’s fake.
