I guess a more fitting term would be "bright room mode" instead of dynamic tone mapping.

Dynamic tone mapping is supposed to look similar to this. Scenes that are below the source peak get some relief from tone mapping, which will make them appear brighter as they follow PQ curve more closely. The other scenes that seem darker are probably being tone mapped. The 2018 models should be following the PQ curve in the 0-100 nits region, mostly to fix the raised blacks issue from the 2017 models. They are known to track the curve properly from the factory.
I would think you would get the best results by leaving dynamic tone mapping enabled. Using a static curve will provide no relief from tone mapping for the entire movie. This would only make sense if the display disabled its tone mapping when confronted with metadata that indicates the source is within the display's brightness. But dynamic tone mapping should already do this without needing any metadata.
I've seen some spectacular HDR on a 2018 LG OLED, so I have no reason to bash it's tone mapping.
