"Black crush" in HDR content, any solution?

[DeeLuXe]

Hi my friends. From the first day I have noticed that this phone suffers from black crush in HDR content. Playing from (internal) SONY player, VLC or Kodi, does not matter.

I've done a comparison with the Spiderman trailer that has the phone in internal memory with the same trailer on YouTube (at 1080p without HDR).

Image config: Aut. brightness off / Brightness at 50% / Image mode 'standard'.

This is the result:

Spiderman trailer 4K HDR:

Spiderman trailer 1080p (without HDR):

Spiderman trailer 4K HDR:

Spiderman trailer 1080p (without HDR):

Down or up the brightness does not affect. It is not a problem of brightness and contrasts. It is Gama problem. A bad implementation of the HDR content. The phone does not allow to modify the Gama range, the video players neither.

This is a software problem. I have contacted other people with the same phone and the same thing happens to them.

Will SONY solve it with any firmware update?

I think I started having similar issue after December system update.
