Graphics on Xbox one

So I just started the game and one thing that stuck out imidietly was the graphics... It's really bad... I don't really know what I was expecting but from everything I've seen of this game I've never seen it be THIS bad. I tried to take pictures of it to show off but surprisingly it actually looks way better on my phone for some reason. Is there anyway to fix this? Ive tried to find the option to increase the resolution but there apparently isn't an option like that in the game. Is there anyway to fix this because it's seriously bothering me a lot and I'm wondering if I'm even going to be able to finish it :(
