    I just noticed one day that these three functions are locked and can't seem to enable them. How may I fix this without wiping my phone?

    That's nuclear option.
    Go to settings >system >accessibility. In that, turn off "color correction" under display.

    Reset the App permissions, it may be that an app or apps or something connected is causing the issue.

    Go to Settings > Apps & notifications > see all apps > select three dots > Reset app preferences.
    Then reboot.

    ⚠️This will not delete your apps data but you will have to provide permissions for all your Apps again.⚠️

    Check if this can help.

    Thought maybe it was a permissions issue. Came across it before where an app that was similar to a system feature overwrote the permission of that feature and became the default app. Sometimes it can be hard to trace which 3rd party app may have done that. Just my train of thought.

    Anyway, also possible an accessibility issue too.

    It is usually caused by apps which have a control over your display settings. For example, blue light filter apps, apps which try to emulate greyscale feature of digital wellbeing, etc.
