I see what you mean. Just checked my RAW file and even on my darkest exposure there is still a bit of the white you are talking about. It was super bright in those parts of the photo. The darkest exposure is greatly underexposed and still had a tiny bit of over exposure in the sky. But the yellow/orange was there in the capture.
I would, it works good as a landscape lens, and I've heard it's a good portrait lens as well. It's wide and you have some zoom which is good for travelling. But if you're looking to buy one, look into reviews about what you need, not just what I say
