Samsung Q82R vs Q80R vs Q80T

[Acckij]

Hello experts,

First of all, would like to thank you very much for the nice and useful job you make.

Can you please help me out to understand the following:

I want to buy specifically Samsung QLED Tv, 65 inch, and I am looking at 80T vs 80R.

Two questions have arised:

1. After made my online research, I have heard, that Q80T is a basically downgraded version of 80R. So shall I stick to 80R in this case? What would you recommend?
2. Our electronic supplier offers QE65Q82R (as there are no 80R models left in Estonia, 82R is offered and he claims, that this is the copy paste the same version, as 80R). Does this piece of information belong to truth?

Here is the link for 82R model : Teler Samsung QE65Q82R QLED 65" Smart - BIGBOX.EE

Thank you very much in advance!
