No. They are not for insider previews. Insider previews from 10240 on are simply the same keys as above. The previews are builds. They are not independent versions of Windows in their own right. There are no "insider" keys now. The only difference between an insider installation and an RTM one is that the user has chosen in Settings to receive insider builds. The only path into the insider program now is to install RTM Windows 10 and then join the insider program.
