Two software update questions LG C9

[lepiane]

Hello. Happy owner of a C9 OLED that I calibrated with RTINGS.com suggestions and I'm very happy. I let the LG update 2 days ago and maybe I'm imagining things but the picture seems slightly worse. Should I go in and re-calibrate? Could the settings have gone back to default?
Thank you

If you've changed any of the settings in your chosen picture mode then "(User)" appears after the picture mode name. e.g. "Standard (User)". If "(User)" is now missing then yes, the settings have been set to their defaults.
