No, technically it is far too cool to be anything but a yellow star, and
too big to be a dwarf.
Maybe if it were 6500K, I'd agree with you on the "yellow-white".
The minimum surface temperature for a white dwarf is 7000K.

We also get a lot of our visual cues from shadows and the
"imperfections" of natural light.
We also get a lot of psychological and physical benefits from the
variations in natural light as the days goes on, and the seasons change.
