I could be way off, but I would venture the guess that the D&G packaging designer was purposefully harkening to the shape of the iconic Chanel No. 5 bottle.
Chanel's No. 5 bottle was considered avant garde when first released (nearly a century ago). At that time, perfumes were done in bottles shaped like birds, and all manner of fanciful packaging. The Art Deco design of the No. 5 bottle was considered extremely forward and as such has certainly become an iconic fashion image (people who nothing about fashion can recall the image of Marilyn Monroe holding her No. 5 bottle).
The D&G bottle is square, and similar in shape and austerity in packaging. As such, it reflects what has gone before (Chanel) but also continues to remake the bottle into something that's still all about D&G.
A comparison....
...Not unlike a RWS inspired deck. Similar enough to be recognizable to the original, but also unique and different too.
