I say it as a guy that's been a hospitality exec for a couple of decades and heavily involved in a group that puts on an international wine competition annually. You will find whites in green bottles, but they tend to be lighter in color than that bottle reflects, though a sparkling might look that dark due to the thickness of the glass. Possible that's what it is, and, if so, then Zenda is a girl after my own heart because the shape of the reflection would indicate old-style champagne tulip glasses rather than flutes. Flutes give you a show, but tulips are better for allowing the wine to open up and letting you indulge in its full flavor. And, while it could be sparkling, the bottle looks more to have a Burgundy or Rhone Valley region shape to it, and the darkness suggest red. But, it's all just pixils and imagination.
