There is a well-known issue in Xperia 1 V which occurs on every unit (10 out of 10 tested devices). It's a screen showing color shift/green tint below certain level brightness (usually the switching point is at ~80%-90%, but some time at 40%-50%) visible the most while showing non-HDR content with dark colors.
There are many videos showing how to reproduce it:

There are also discussion on Reddit with a technical guy assuming that this is caused by the fact that OLED screen is not calibrated well and he had fixed the same issue on another device with OLED screen by modifying kernel, particularly copying some screen calibration parts of code from another manufacturer.
I would like to submit a bug report and get a ticket number so everybody could track the progress of this issue. But I can not login properly on a Sony website to contact support so maybe it's possible in community section?
