Some of us are also aware that physics dictates that the area closest to the light source is brightest, and so our mind just equalizes the color. When I sit in a chair beside a lamp, and read a paper book, there is gradation of brightness across each page, and in the valley of the spine. So I expect the same gradation across all physical objects.

That said, I would make a lousy painter, because I don't often notice the many different shades of green within one tree. The differences that are due to physics, lighting, etc: my mind wipes those away, and tells me "yes, this is a three dimensional object. Color variations are how I know that. Now you can forget those color variations, because they are normal".

So what some term "more discerning", strikes some of us as "far too picky". It's just semantics. So don't yell as us for not caring, and we'll try not to yell at you for caring, that the color changes a bit across a page. My minds tells me that such slight color changes are normal, because, well, "Physics". So I dismiss it.
