Might I ask how much experience you have with the world of professional color sessions? I have been in film/video post pretty much since graduating high school, so I have been a part of prepping content/materials for a color session for decades, but have also spent several years working at a post house that only did color correction. I'm guessing that it is you that has the incorrect understanding of what goes on in a color grading session. If you want to go around thinking that applying a LUT is all that happens in a grading session, then you might as well think that anyone that uses Wix or Squarespace is a web designer, or anyone that assembles Ikea furniture is a craftsman. Your definition would be very skewed.
