Nah, I was one of the “advanced” ones who “got” everything and could recite like a scholar. I don’t think it helped. It’s truly unrelated to the real advancement in spirituality.
There are some nuances here that aren’t worth going into. Generally, the Zohar is for drawing the Reforming Light. But we can say that whatever Light cannot enter the Kli remains outside, as Surrounding Light.
All that is written about in the Zohar are forces. Also, Rabbi Chiya is a force and not a person.
