To HDR or not to HDR

I'm showing comparison of the same video in HDR and not. For the purpose of this recording I have fixed camera settings to ISO 100 and shutter time 1/60s. This way we can see any differences in how image on the same display shows differently.
The original is in Rec.2100 (HLG), output was set to Rec. 2100 (PQ), and format to UHD DNxHR HQX 10-bit. I uploaded that to UA-cam directly from DaVinci.
