I don't think most viewers consciously notice these details. Nevertheless, it would have been a more powerful film experience if they had painted a much more sterile-looking and sterile-feeling Krypton, rather than just telling us that Krypton was sterile.
Yeah, it was cool seeing Krypton come alive the way it did, but in respect to the theme that Krypton was a dead world in every sense (planet dying, society dying), maybe its visual vividness could have been toned down, e.g. omit the dragon.
Saying that, this isn't a knock on the film. A preference than any real issue.
