My take on it too, from what I've been able to gather so far. Also, any
filters in the colorimeter will age, or the display's own primaries will
shift in time, making obsolete any firmware fix (non-filter-based) in the
colorimeter.
Having colorimeters that are precisely tuned to the primaries of each model
on the market is probably a practical impossibility. All the more true now
that so many wide-gamut displays have become available, among them even
cheaper non-IPS models like the Dell UltraSharp 2408WFP (which very closely
matches AdobeRGB).
In all fairness, though, and this is from personal experience, the
DTP94/Optix XR colorimeter seems to have no problem calibrating and
profiling that Dell monitor I mentioned earlier for a client of mine, and
doing so with results that appear smooth, neutral and precise (or let's say
say that neither I or my client have yet found any problems with them).
