I think you can mention all 3 for more effect, HDR10+ is also well documented, and I did ask Citizens Advice on HLG and that would be up to coutrt may be but they think you could have an argument for it with the articles. Samsung would have to deny under oath and that is the difference, and why it may be good to push the issue, and it may help to push Samsung in the right way. You can ring the Citizens Advice and you can start the process.
I was just reading through the same as you posted. So, I suppose JL (in my case) have the right to offer a replacement. However I suppose I am aiming for a Right to Reject although JL might try reduce the refund in respect of a "deduction for use". I wonder what that might look like.
Any thoughts on whether its worth including the HLG and HDR+ stuff? I am currently thinking no, just because of my purchase date (aug 16).
I think if it was to do with a repair then again I think they can take into account the time you had owned it. With the mis selling it was mis sold from day one and can not be repaired so you are entitalled to a full refund. That is what I recieved when I returned my JS8000 for mis selling to Curry's, after owning it for over 6 months.
Also it won't hurt to ask using the templete from the link I just put up, and if lots of owners do it again it may force Samsung to do the right thing, if nothing else it will only cost you a bit of time, and may be a TV that does BBC Iplayer HLG.
Where was the template? Probably can't see for looking...
It's more of a tool. Just fill in the details and it will advise you. Really easy to use.
I have gone through the tool and it is useful. I have been able to improve on my draft to go to John Lewis. Thank you!
Spread the word and keep us all updated, and keep posting that link for every one else. Thanks.
