LG have add a new feature to there 2018 oled line , this feature adjusts the luminance of static images such as logos within content to correct potential picture quality issues.

This is a simple feature that can be switched on or off just like pixel shift . 

This feature should be added to 2017 sets if not all older LG oled models as this will reduce the risk of screen burn .

 Web OS 4 maybe added to 2017 sets with this feat
