Have ou tried adjusting gamma yet? Not sure if it'll help or not, but give it a whirl.
The planes are sometimes actually colored in an attempt to blend in, and from a front of rear view they can have a very small profile, which can combine to make it tough to see them.
I'm seeing the same thing on my end, but actually like it, because I think it's realistic, and I'm fairly certain the effect helps me at times too.
One other thing you may consider trying is reducing your resolution a notch or two. I prefer mine to be higher because I think it looks nicer, but I did notice a definate "shrink" effect on objects when I did it at first.
Of course, a giant monitor would probably help too, hehe!
