Same here, I see details when I concentrate on seeing details, but otherwise don't really see anything. For the apple thing, I can see a vague concept of an apple but when I focus on say seeing the shape and color of the stem the rest of the apple just fades or blurs out.

I also read a lot of fiction and I almost always skip long winded descriptions of how things look because I won't remember them and they don't mean anything to me. Descriptions of things like smells, tastes and textures though are different.
