What strikes me, though, is that when I look at the light outside of my

Because your eye tries extremely hard to interpret a very wide range
of light as "white"
I know color is next to impossible
to relate acurately in words but the color sensation I am getting from
starting at at white surface lit by direct sunlight right now is not as
yellow as Photoshop would have me believe by converting absolute
colorimetrically a D50 Lab 'white' to a D65 'white'.
Because you're looking at a simulation of what a D50 'white' would
look like when your eye was adapted to a D65 white. When you look at
the white surface in your direct sunlight, your eye is adapted to
that sunlight...
And no, I have a
Munsell FW-100 hue test here and I am glad to report that, despite the
coutless hours I have torn my eyes looking at jobs and retouching images in
Photoshop on a CRT in the past, I still enjoy a normal color vision.
There's no reason to suspect your color vision based on this
phenomenon. I'm pretty sure most people would see the same.
