Up Close details.. where did they go?

I dont know why they made things look worse up close or zoomed in but that
was one thing that i thought reach had going. I mean just go to any map on
reach and you can screws in the walls or copper pipes that looks amazing in
detail even when zoomed.

When i look up close to many objects in halo 4 they just appear dull and not
very detailed.

Was there a reason for this for space or something?

Go to adrift and look at the hose on the ground kinda by one of the
flag spawns and you will see what i mean.

This by no means ruins the game for me because its amazing but why did this
happen?
