Vero 4K KODI not passing (some) HDR metadata

Steering the conversation away from sassy axioms, what is the practical impact of not passing MaxFALL/CLL metadata? I’ve noticed that oftentimes HDR content from OSMC appears dim or underexposed, especially in midtones. The issue is not present when watching the same content via a different source.

Is that consistent with absent MaxFALL/CLL metadata?
