Which OS ? Auto-upgrade then maybe Fedora ?
The color cube value has been reinstated in the development version, currently Gimp 3.2.RC1 but now in the histogram dock.
Apart from that, no problem here, Kubuntu 24.04 / Gimp appimage , converting RGB to Indexed and I have not noticed any excess writes to disk. Maybe if you give more details someone might spot the problem.
