Thanks, appreciate the response. But it does not really answer the question about the function of MultiProfiler vs Spectraview
SpectraView uses an instrument to conduct the process, MultiProfiler doesn't. It accesses some data of measurements done by NEC using a very high end spectroradiometer and then it updates itself based on display aging and such. You'll probably have more control in the end, using the SpectraView and instrument approach but you're not forced to do so.
