You do realize that a number of those "mind-numbingly" awesome screenshots that are taken are done with settings that make the game unplayable, right? There's a lot of ini settings and graphical mods that I use where I can make absolutely amazing screenshots but can not actually play the game because it breaks a great deal of it.
You also need to specify what "more" you want. Higher res textures? Longer detailed view distances? Better ENB? There are tons of improvements that can be made to Skyrim. And strangely enough, looking at S.T.E.P, I don't see too much of an improvement.
