@Moanygit was given one (a firestick lite, 1080p) by my retailer (Curry's PC World) however getting offered it was like pulling teeth. Despite them having in their specifications for the TV that you simply need to be in the UK. I think they had "Some services are coming in 2021" however the "catch up services" listed iplayer, all 4, ITV hub and 5.
Speaking to the manager was like pulling teeth, I asked for an extended returns window into mid January which their manager (he was quite rude) outright refused and said that the TV could only be returned if there was "a fault" and that because its android TV its not a fault as I could use my phone to stream. This went on for about 10 minutes with him basically trying to pick holes in things until finally he said he would get a firestick. He came back with a firestick lite and when I asked if it did 4k his response was "no but most programs on the services requested aren't in 4k"I simply responded with "most but not all" to which he basically told me it was "leave the TV back today or take the firestick"
I accepted it though made it clear (I was there with a member of family too so two people heard it) that a firestick is a temporary solution though their site clearly has incorrect advertising and I would return in the new year if the TV wasn't updated as that would invalidate their terms of sale.
As for a firestick. You'll get the services you want. The quality of the image will depend on what type of firestick you get and you'll probably be given the cheapest unless your retail manager isn't as aggressive as mine was. Just be sure to not put anything in writing that may in the future invalidate your returns policy if the TV was advertised to come with these services. It would also be wise to download an offline version of the Web page containing retailer's item spec if they list these services and then email the downloaded webpage to yourself in case the Web page is changed in the future. That way you can say that these features were advertised to come out in 2021 when you purchased it.
Using the firestick lite now through my AVR. Picture quality isn't all that great, it's a bit clunky, it does have a voice remote which means navigating menus isn't too difficult. All 4 and ITV hub are stereo only, not 100% sure if that's an all4 thing I could swear they did 5.1 surround last time I used one of the two I got 5.1 though I might be mistaken, the firestick lite does do dolby digital+ 5.1 on Netflix, though you get Netflix with the TV and better sound over eARC so that's not a concern. Can't speak for iplayer, I don't have a TV licence so no iPlayer or live TV for me. The other 4 catch up services are perfectly legal to use so long as you don't watch live (which includes all +1 channels) streaming after something airs is good enough for me and saves me a couple hundred pounds annually.
In the end its a third remote and a workaround, even if your retailer gives you the best firestick out there. The retail manager I got tried to claim that the TV did support the advertised services because I could cast via my phone. That would be true if the TV came with a phone.
I hope Sony releases the update in 2021. Their customer care and support used to be great, they gave out free games when PSN went down due to a denial of service attack for a few days. That's the customer support I remember.
