Same problem with mine. It would appear that Google/Sony bought the rights to make non google/sony Smart TV's rubbish.
OFCOM are too rubbish to do anything about it. Here is my response from LG - oddly it took a long time to get the truth out of them.
---------------------
In regards to this, unfortunately this TV does not come with the ITV Hub or All4 Application, as ITV and Channel 4 had signed an exclusivity deal with another major brand at the time of the release of these TV's.
Currently, this contract is still under-way, meaning we aren't able to bring these applications to our other TV's as yet.
Some of our 2016 range do have access to these applications, due to the release of Freeview Play.
This means that we are able to implement it on these systems, however as it stands at the moment, there are no plans to implement on Freeview Play onto any of our TV's that were released before 2016.
I apologise greatly for any inconvenience this may cause, however I hope this explains the situation a little clearer for you.

Thank you in advance.
