How to make skills of depth/presence/development legible to others?

I've had this fantasy for the past year of creating a YT live stream show that features different teachers, facilitators, healers of different modalities and somehow make legible what they're doing to a larger audience.

Often, my experience is people enter the spiritual/healing/relational arts world from a really intellectual place and work down.

For example, 
- Read a book about the topic (NVC, IFS, meditation, etc)
- Practice it mainly from their head (sentence stems)
- Do a milllion reps and somewhere realize, this is also an embodied awareness practice
- Start getting into the weird woo territories of energy, spirits, intuition, etc

But to a beginner, there's a pre-/post- issue where you can't really tell the difference between a really deep facilitator and a really confident charlatan.

Furthermore, you aren't really that interested in the really deep people. A lot of my friends have been practicing for 15+ years and won't seem impressive on a podcast or a stage like the big head intellectuals and academia folk (Brene Brown, Lex Friedman, Huberman, etc) but they are geniuses in their own craft.

So, how to illustrate these skills that don't translate as well into written or spoken existing mediums?

hope that's legible what the q here even is
