There is but the next update is just a sandbox update adding in some more sex scenes between, then DLC probably a year from now. But the story is done.
Steam is $16 no clue if DLC comes with that I doubt it and will be probably a year from now, and you don't have to pay for the next update, and Elite is $40 but those scenes are non-canon and have nothing to do with the story.
If you want to own it, well saves are fine between both so, you can always just pirate the elite for the elite gallery scenes
