We show that it is instead a spectroscopic probe of the carrier distribution: because $g_m$ weights the spectral current $j(E)$ by the gate-voltage derivative $\\partial f(E)/\\partial V_G$ and integrates over energy, it is sensitive to the \\emph{shape} of $f(E)$, not merely its integrated weight $n$.
