You can tell when the colormap has been replaced by polling
with XListInstalledColormaps.

A more clever solution would create an off-screen window that
tracks the currently installed colormap; changes would be signalled with
ColormapUninstalled events, at which point you'd switch the window's
colormap to the newly installed one and await another change.

If this simple kludge works out for you, I'd say we're much less likely
to even bother with new extension request as this will be reasonably
efficient.
