Superman Easter Egg In 'Justice League' End Credit?

The post-credits scene of Justice League was one of the best movie fans saw this year.
The scene was good enough to be nominated for one of Comicbook.com Golden Issue Awards.
While the film is one of the most polarizing of the year, fans certainly enjoyed the end credit scene.
In the scene, Deathstroke (Joe Manganiello) and Lex Luthor (Jesse Eisenberg) are enjoying wine on Luthor's yacht.
The whole bottle design looks like the black and metallic "Death / Return of Superman" costume.
