Dark Bars on certain 4k movies

Thanks for the advice. So really only Sony themselves could fix this then? I wonder if I could get any traction trying to pester them to fix it.

I had a hard time finding any mention of this issue online. If you have any kind of reference to other people experiencing this problem (for example in GitHub issues or the likes), could you post it here? Would be helpful if I reach out to Sony.
