If you are watching telly in a sunlit room at midday then any tv will look shit.
I won’t watch stuff I want to enjoy (film) in the day as I know my big telly will be affected by glare (never mind the general brightness).
I just watch it later in the day. I wouldn’t buy a brighter telly to solve that issue.
If brightness is a deal breaker for you then it matters. Would depend on how you use it and when. Our 65 inch oled is in a south facing room and I don’t care it doesn’t go any brighter. It’s bloody good when it is good, and when it’s not (summers day) I just don’t watch it / shut the blinds.
Seriously, I have no regrets, It is a lot of cash and I was initially worried it might be too big and overpower the room but it is fine,
I watch mine mainly through a Sky Q box if you are just relying on the LG Apps I am not sure all freeview channels are available. Best check that you will get all you want.
Hope you are not relying on the speakers in the TV though
Once it’s in situ she’ll agree about the size. They are so neat / thin it’s not an issue. Getting it on the wall, not too high, not above a fire place or suchlike, high whilst not seeing the wires are the things to concentrate on.
It would nearly fill the distance between speakers, which she isn’t overly keen on.
Eventually it would go in to the back room which will be the TV room, when we finish renovating.
