It is, but it's not a hard and fast rule.  If you are running multiple
local X consoles, for example, they can't all be :0.0.  I've also seen
different identifiers when one X session is hung and/or doesn't finish
cleanly before a new one is brought up.

If DISPLAY is consistently set to :3.0, perhaps it is a Fedora-specific
thing, and it'd be best to ask people more familiar with Fedora.  If
they have made changes, those changes may not have propagated to RHEL/
CentOS yet.
