Graphics store page vs actual ingame

Graphics look way better in the pictures of the game in the Store :: 7 Days to Die General Discussions
I have 300 hours on the game so I kinda know about the game and all that, but I recently saw that the steam pictures changed to way better looking of how the game is, and I thought wow they actually changed those graphics which are a pain for the eye? let me take a look.. But no is still the same, they only truly changed the pictures of the game in the store instead of just make better looking graphics.. I mean the game is great and all but dam I wish it had better graphics man..
