xyx2rgb * .01?

[mighdoll]

Presumably drop the * .01 here in xyz2rgb.glsl:

const mat3 XYZ2RGB = mat3(
     3.1338561,-0.9787684, 0.0719453,
    -1.6168667, 1.9161415,-0.2289914,
    -0.4906146, 0.0334540, 1.4052427
);
vec3 xyz2rgb(const in vec3 xyz) { return XYZ2RGB * (xyz * 0.01); }

but in rgb2xyz.glsl:

const mat3 RGB2XYZ = mat3(  
    0.4360747, 0.2225045, 0.0139322,
    0.3850649, 0.7168786, 0.0971045,
    0.1430804, 0.0606169, 0.7141733);

vec3 rgb2xyz(const in vec3 rgb) { return RGB2XYZ * rgb;}

I've been adding tests for the WESL translations, and Claude spotted this while reviewing.

Looks like xyz is intended to be 0-100, so the fix would be to rgb2xyz then..
