The show Stephen does from home harkens back to his old "Colbert Report" show but yet without him having to act in character. On the regular (televised) show, he quickly devolved into just another comedian doing a monologue. He blended in with the other Late Night hosts. It was less clever, less full, and just plain less funny than what he has been able to do in his opening segment from home.
If there is one reason to hope that quarantine continues, it is to keep Stephen at home doing his opening segment as he has done these many weeks. Please let him do it that way when the show reopens.
