In 2016 I wrote a paper for Thorn Lighting which turned into Masterclass for the Society of Light and Lighting. It was based around getting the balance of light in a space right before you added worries of Human Centric lighting as it was being called then.
My take is that if you don’t light the task, space and face then it doesn’t matter what technology you use or how you vary light over time, people will not feel good in the space. You can download a short version here Comfort Management White Paper
With a bit of luck you can find more info from Thorn, but I think they dropped the idea after I left.
