Yes, it can’t hurt. I’m not 100% sure. I’ve used the original name, but Plex may use the Client name from inside the XML.
The Plex guide also mentions how to confirm that it has taken precedence over the built-in profiles.
From the guide:
How do I know if my user profiles are being used?
If you look at the contents of Plex DLNA Server.log after PMS starts up, you will see entries along the lines of the following:
Jul 08, 2013 13:16:18:024 [47244] DEBUG - Overriding system profile Xbox 360 with user profile
Jul 08, 2013 13:16:18:037 [47244] DEBUG - Reading user profile Xbox 720
The first line indicates an override, the second that a new user profile has been found. If the server has a problem parsing your file, it will report an error and continue execution. So it’s important to double-check the log after you’ve made edits to your user profile files.
