So how would you reconstruct a continuous, irregular curve of spectral
energy distribution from just three data points?

It's possible if the curve is a portion of, say, an ellipse.  But the real
world curves aren't, so you cannot reconstruct them from three data points.
And because of this, you cannot use RGB values to reconstruct the
information you would need to accurate simulate the spectral response of any
arbitrary monochrome or RGB sensor or film.  The required information just
isn't there, period.
