Exactly. Well, maybe 4K is also easier to understand. However, even the streaming platforms seem to disagree: Amazon calls it UHD and Netflix 4K. But it's also *almost* the same thing.

Yes, the TV is UHD (3840 x 2160 pixels).
Explanation: 4K (4096 x 2160 pixels) is, when you get right down to it, not a standard for TVs and monitors but for production and cinema projection. Marketing and advertising, on the other hand, have led to the fact that we commonly speak of 4K devices when referring to UHD devices. HDR has nothing to do with the number of pixels but brings a higher colour spectrum and more luminosity (someone else can certainly explain this better or correct me).
