Eh, I am as pumped as the next guy but it is definitely a nerd reach to analyze too much int he film as if it will ruin it. It's not like I posted a death scene or a critical scene in the film that will completely kill the movie. Again, i still truly believe that image, even without the backgrounds and stuff you analyze up the whazoo, will be released to the public via trailer, trading cards, promo pics or action figure.
And don't take the "nerd reach" as an insult, I do it too but just not to the same extent. I am very anal about spoilers too but that really doesn't seem like a big deal. Even I see it as too much of a reach to read too much into it. It's like seeing Black Panther (in costume) fighting Bucky and Cap in set pics, I've been waiting for a Civil War film to come out ever since the comics were released but I am not going nuts because it revealed an encounter between the three.
But again, I followed your wishes and spoilered it so whatever.
