I was lucky since it came as a replacement for another Philips TV that couldn't be repaired. Philips handled it well. Before, I didn't have a smart TV, but I also didn't have a good picture quality even though it was also 4K. This TV is incredibly good, with a brilliant and clear image. Once you experience HDR, you don't want to go back, everything looks much better. Netflix plays flawlessly up to 4K HDR, provided that there is a suitable internet connection. The ambilight is also impressive, but it can be tiring, at least for us who are sensitive to it. The HDMI connections, although there are three, only two have HDR. The menu is slow, and it takes a few clicks to change the picture mode; it would be good to have a direct button for this shortcut. It is also a good monitor, both with the PC and the Xbox One S, where it fully utilizes the capabilities of 4K HDR and Blu-ray. One drawback I noticed with the PC is that it doesn't sync the video well from some movies, as well as from Netflix, always through the PC. What I mean is that if you have the refresh rate at 60 frames per second, the image seems to not sync well and shows a slight delay. I solved this by switching to 24 frames per second refresh rate when watching videos from the computer; I couldn't find another way. Overall, I am completely satisfied, and I definitely recommend it, and I would definitely buy it again.
A relatively useful update. Because HDR on the computer is strange, I recommend using Netflix on a computer with the EDGE browser, as it supports 4K HDR. CHROME on Netflix only provides 720p. By simultaneously pressing ctrl shift alt Q, it displays statistics that also include the bandwidth. If the colors appear dull, you can adjust the brightness and contrast from the NVIDIA control panel, which made the image shine for me.
