MATLAB: Need to Convert RGB color space to L*U*V* color space , Please tell am i correct with this code

color spaceconverting rgb to l*u*v* color spaceImage Processing Toolbox

%convert to RgbI image in RGB to XYZ
XYZTransformation = makecform('srgb2xyz'); 
XyzI = applycform(RgbI,XYZTransformation);
%seperate X,Y,Z

X = XyzI(:,:,1);
Y = XyzI(:,:,2);
Z = XyzI(:,:,3);
figure, imshow(X) , title('X');
figure, imshow(Y) , title('Y');
figure, imshow(Z) , title('Z');
xyz = cat(3, X,Y,Z);
figure, imshow(xyz) , title('xyz');
%convert to XYZ
labTransformation = makecform('xyz2uvl');
luvI = applycform(xyz,labTransformation);
%seperate X,Y,Z
u = luvI(:,:,1);
v = luvI(:,:,2);
l = luvI(:,:,3);
figure, imshow(l) , title('l');
figure, imshow(u) , title('u');
figure, imshow(v) , title('v');

Looks right to me. Just realize that any lab or luv or any other colorspace values you get from "book formulas" are not going to be the same as the "true" values you'd get from a spectrophotometer or spectroradiometer. This is because your system is not calibrated and it assumes the values are sRGB which is not true.
