My personal experiences matches this as well. I've seen it a bunch of times. It seems to be much more engagement than harmonious which like you observed was pretty packed for the Stargate viewing area but elsewhere could be sparse.
I was surprised that
@lentesta revealed that Harmonious ratings were pretty favorable. I liked the show very much, probably more than luminous but I do like luminous. However there was no doubt the show had a huge following of critics online. But the ratings revealed showed that overall it seemed to be doing pretty well with the guests so I'm surprised that Disney moved forward with changing it. Regardless as someone else pointing out I think luminous grows on me with each subsequent viewing. I too have gone from it's good to its very good. I'm probably going to fall in love with the show with a few more viewings.
