If anyone is still experiencing issues with the webOS Disney+ app (and I suspect many if not all of us still are) such as the lack of 4K support, 5.1 audio support, or as in my case with the 86UH9500, both, please see LG's response to my inquiry into these issues:
We appreciate you for patiently coordinating with us regarding the current application status of your LG 86UH9500 TV, Xxxxxxx. It is our goal to ensure that you are able to utilize your LG product at its fullest potential so let us assist you with your inquiry today.
In response to this, according to the specifications of the unit, the LG 86UH9500 TV has been designed with a 4K UHD and Surround Mode feature. However, if the Disney+ app is the only application that does not output surround sound, please be advised that both the content being played on the TV and the applications should also support this feature as well. This case on the capability and support made by the developers of the Disney+ Application needs to be raised directly to them so that they can make the necessary updates on the programming and utilize our TV’s 4K UHD and Surround Sound features that are already available in our OLED Television. You can reach Disney+ Support Line at 1-888-905-7888 for additional support and assistance.
So, as expected, LG is pointing the finger at Disney to resolve these issues. This makes sense as my inquires into the availability of the Disney+ app from LG before the launch directed me to reach out to Disney+ as they, not LG, are responsible for it.
So if any of you out there have Bob Iger on speed dial, can you give him a ring?
Thanks!
(PS yes, LG incorrectly identified the UH9500 as an OLED model when its an LCD, but I'll let it slide)
