@wuwei DisplayCAL and ArgyllCMS for colour calibration, and veracrypt for disk encryption. They are in Copr repo but I cannot get them installed on Fedora 33 beta.
DisplayCAL is in the stable version, you have to be paitent if you're using beta
ArgyIICMS as far as I know works only on python2 so that's out of the picture until they update sadly
Veracrypt uses a weird liceance and since most users just use built-in LUKS it wasn't included just to be safe (again as far as I know)
Seems to me that an older version of Fedora could suit you better(or even a different distro)
