the settings are part of calibration, yes they are not unique to YOUR panel, but they provide a good baseline to start from.
What you should be more concerned about is fact that OLED has a shorter lifespan and even if you calibrate this panel now, in a few years your calibration settings would likely be much further.
tbh: I wish you the best of luck in regards to the longevity of your LG tv, as I haven't had much luck with this brand in the past.
