Steve,
Sorry if I'm messing up a little bit, but neither CIELAB or CIELUV are
considered "perceptually uniform" nowadays. CIECAM02 is considered a
more advanced option today. But the "perceptually uniform" is only
relevant if you are interpolating colors. If you are just looking for
color difference formulae, choose dE2000 or dE94, using CIELAB as a
colorspace, and stay with the chosen one.
Best regards,
Lorenzo

I understand that the CIELUV space is still preferred by many working with
video. In fact I've heard one commentator say that CIELAB is preferred for
reflective media applications but CIELUV is preferred by those working with
emissive applications. I find such comments puzzling as I had always
thought that CIELAB had proven itself over time to be the more "robust" (by
which I assume people mean "more perceptually uniform") colour space
