What I mean is that it belongs to the "set" command output but
should not be in "printenv" command output.

It is a useful shell variable to help interactive use, but it
causes trouble without benefit when exported to the environment
(breaks scripts you invoke without you knowing).  Calling such
a shell variable "an environment variable" is spreading trouble.
