You seem to be interpreting L as a polar coordinate, which is rather
unconventional -- and as a matter of fact doesn't make much sense, since
it causes all grey tones to collapse into the center.

The official CIE LCh colout space is cylindrical in nature, not
spherical (though the visible gamut under D65 might take on a somewhat
spherical shape).
