I see nothing wrong with your stats that indicate a motion problem.  Is your display native 60Hz or 120Hz?  Your screen shot does not look HDR although I see it is passing through NV HDR.  It's also windowed instead of fullscreened.

This is playing back on the TCL 55R617. The set has a native refresh rate of 60Hz, and an effective refresh rate of 120Hz using TCL's CMI (Clear Motion Index). 

Whenever HDR (or Dolby Vision) content is played back on this TV, there is a short (few seconds) pause where the screen goes black - I believe it is the set switching from SDR -> HDR/Dolby Vision. At that point an indicator comes on at the Top-Right of the screen with a label "HDR" or "Dolby Vision" for 2 seconds. This does happen when I play HDR Content in MPC-BE using the settings as described. It also happened when the above "Oblivion" UHD HDR video was played back for the Screenshot. I used the Windows 10 "Snipping Tool" software for creating the screenshot. What you're seeing the screenshot is definitely not what my eyes see when I'm viewing the video on TV. It's looking much paler, washed out in the screenshot. I do believe HDR was activated & working during playback. I don't believe the screenshot is displaying it correctly. Possible image compression or whatever tech Snipping Tool uses. 

Yes, in order to take the screenshot I had Alt-Tab to Snipping Tool, which did bring the video in Windowed Mode. However, the issue that I described was in full screen playback. Windowed mode was only switched to for the sake of taking the screenshot.
