Are you talking about the test patterns with the little girl and colored toys all around her? If so, then there is no color clipping. I can see all colors and gradients distinctively.
Lowering contrast each step down to 40 does not have any impact on clipping over the default of 50.

So you have clearly defined steps between 2000 and 4000 nits, thats interesting. I wonder if Vizio calibrates cast only, then universally apply the settings across the board.

FW 2.1.7.1 calibration settings

Below are my calibration settings for SDR on firmware 2.1.7.1. This is a complete Grey Scale and Color Gamut calibration using an i1Display Pro. Post-calibration charts from HCFR are attached. Signal source for SDR calibration is madTPG being driven by HCFR. I verified the results using R.Masciola's Advanced Calibration Disc sourced by an Oppo UDP-203.

In the SDR RGB curve you can see a bump at 15% white. The 11-point white balance tuner on the PQ65 doesn't allow me to tune that out.

In the HDR10 RGB curve there is a bump at 75% and dip at 85%. Using the 70% and 80% controls allowed me to flatten those out, but doing so led to visually obvious posterizaton in bright areas so I reverted the 70% and 80% settings back to default.
