You are misunderstanding. I don’t get better results with YCbCr, I have analyzed the RGB and YCbCr signals of the ATV 4K. What my analysis is telling to you is that with that device the signal is fluctuating. That means that one pixel has a value and the next one has another and so on. The YCbCr signal resulted slightly better because, probably by chance, I caught the right pixels! Maybe if I repeat the test RGB would get better results? Who cares? It will never be bit accurate! Human eye can’t notice that because it stays under dE of 1, but that just adds to measurable calibration dE and not directly measurable probes dE. Moral of the story: i1D3 not profiled to a reference spectro (I know baller02 got his i1d3 profiled to a Jeti) + not accurate TPG dE + normal calibration dE = not accurate TV/Wasting time/funny hobby/training.
No, there’s no discussion but not because I don’t like to argue (I’m Italian like you, we are masters of discussions) but because when things are measured scientifically there’s nothing to discuss. Things are like they are until someone demonstrates scientifically the contrary. But again, I’m telling you that because I’m trying to help you, probably even with a bit accurate TPG you won’t get overall accuracy because of your not profiled colorimeter and possibly your C7 got one PM more accurate OOTB.
