So I'm super confused. From TCL marketing All reviews look at the American versions very rarely the European ones. In several places on the forum they say that they are the same but as far as I can see it is not so, for example the YA9 has Gemini and the K9 does not, also the YA9 has a 98 inch model and the K9 does not. Can someone familiar with TCL marketing or who has touched the 4 models or is simply aware of the models explain it to me. I am in Europe and I am looking for an 85-98 inch TV. I am trying to choose the best for the money to replace my 77 inch Samsung S95d. I have settled on TCL after having a bad experience with the Bravia 9 (otherwise it was a very nice TV) and this discrepancy in the models is super confusing and misleading, the prices are also hugely different.
Current prices at the moment:
98ts8k - 3570 EUR
85ts9k - 2155 EUR
98ts7k - 2652 EUR
98b11k - 5712 EUR
98C6K - 1917 EUR

But I say this informatively. The main question is what are the differences between the American models QM8K-QM9K // and the European ones C8K-C9K.
