Restoring 5 GHz Wi-Fi on an LG C5 by changing its webOS region

An LG C5 TV's 5 GHz Wi-Fi capability can be restored by changing the device's webOS region configuration from Middle East to another region like EU, despite the hardware supporting the feature. The restoration is achieved through LG Developer Mode and does not require firmware updates or root access, though it may affect other regional settings like tuner behavior and available apps.
