RTMP video quality is disappointing

The video quality during RTMP broadcast is 3 times worse than the original
here is an example: rtmp litchi - YouTube

Who uses RTMP - share your thoughts.
Are you satisfied with this video quality?

I have been using Litchi for livestreams with my mini2 . I found the quality excellent live to Twitter and Twitch . Not tried YouTube.
Here is a link to my last livestream.
