I have an LG Oled but that feature is not an automatic one, nor it is recommended to do it every day. Maybe LG shifted policy on it to activate it automatically at a tight interval on never models (mine is 2021 model), but tbh I haven't seen it necessary yet, although I have used the TV both as a TV and a PC screen with constant interfaces, albeit taking care as to rest the screen regularly via watching movies, adjusting brightness, and using that offline refresh feature once in a month. I believe it is fairly acceptable to turn off Oleds completely, unless you want absolutely no responsibility on keeping them healthy.
