<upd_detl>sankoku lists 奢侈 as 文(couldn't say for 奢侈品 necessarily...), and it's statistically less common. Otherwise these appear essentially the same. Kanji is luxury+luxury+good, not unlike 贅沢品.

No inherent objection to "non-necessity", but it seems like more of a defn./synonym than a gloss given the kanji, and wasn't on the xref.  Seems like they should agree(maybe add non-necessity to the xref if that is preferrable).  

nikk says:
奢侈品: 生活必需品以外のぜいたく品。おごりの品。.  &lt;-- outside-of-things-needed-for-living 贅沢品
but nikk also says:
ぜいたく品 。生活上直接必要でない高価な物品.  　&lt;-- not needed for living high-priced goods

So, seems like a bit of redundancy in its definition, and "non-necessity" is definitely contained in the English term "luxury good".</upd_detl>
