There is an updated pull request by kruceter against master on the void-packages repository

https://github.com/kruceter/void-packages dispcalgui
https://github.com/void-linux/void-packages/pull/40420

dispcalGUI: update to 3.9.8, change upstream.
dispcalGUI is not maintained by its original authors anymore.

The significant advantage of the fork is python 3 support which excludes python 2 from dependencies (related to #38229).
