I connected two portable LCDs I have that support HDR. Both LCDs didn't automatically detect HDR and looked washed out initially. I had to manually change them to HDR. The signal according to the AVR was...

  Resolution: 4K60

  HDR: HDR10

  Color Space: YCbCr 4:4:4/BT.2020

  Pixel Depth: 12bits

  FRL Rate: ---
...for both the LCDs.

Here are their specs:

These LCDs definitely don't have the same range as the OLED! They seem almost equivalent to the OLED with HDR off. With the HDR off for both the desktop and LCD, the HDR video seems flatter. I could increase the monitor's brightness to match the planet when HDR is on, but space would be washed out. I could lower the brightness for darker space but the planet becomes muted. When HDR is off for LCD and desktop I do still see a difference between Youtube's HDR and SDR videos. For example, at the 19s mark I cannot see most of the debris scattering between the viewer and the planet in the SDR video. That should be the case for you too.
