I have seen it recommended when Dolby Vision calibrations don't seem to take hold/go wrong. But John already responded with a recommendation.I’m not sure how the LUT would load without re-doing the calibration, since Calman was already disconnected leaving nowhere for the LUT to load from. I don’t think I can evaluate whether the undersaturation of color is occurring until after I’ve unchecked “Enable Calibration” and I’ve disconnected from the iTPG. I was short on time last night, so I’ll re-investigate when I have more time. I do know that I didn’t have this issue my previous calibration which was done with 2020 R2. I may end up having to redo the calibration with 2020 R2 unless I figure this out.
Update: I power cycled the TV without re-doing the calibration, and no change.
I took a couple of photos to demonstrate the difference. Of course they don't exactly match what I'm seeing on screen. The first image is with uncalibrated HDR Technicolor Expert. This is the approximate color saturation level I'm expecting for HDR. The second is HDR Cinema calibrated with 2021 Beta. In reality on screen when in the calibrated Cinema mode, the liquid in the glass and the pomegranate seeds at least slightly closer to the brownish color of tea than red.

This is closer to what it looks like to me on screen:
