I called Samsung about this, and the tech I talked to confirmed that
something like this is true.

In passing let me comment that I used their Natural Color Expert with
their Huey under Windows in Calibration Mode, and produced a
calibration/profile, but I didn't much like the result. Under Linux, in
Custom Mode, I produced a calibration/profile, described in another
posting, which I liked much better, even though I made no effort to
reduce the DE to locus by manipulating the RGB values.
