Will this tv give me the best of the best for HDR 4K ps4 pro stuff?https://www.expert.no/tv/tv/sony-kd55xd7005baep/p-413217/
If you want the best of the best chose between LG E6/G6, Pana 902DX, Samsung KS9590 and Sony ZD9. I would not consider the ZD9 due to software problems and my short impressions at a friends and an electronic store (awesome image quality but many little flaws that are not acceptable for that price). Out of the other three it depends if money is tight. If so get the cheapest one, if you want a little bit variety regarding HDR standards and the (imo) best OS get the LG. All of these TVs are pretty amazing so you will be satisfied either way.
If the TV can't be that expensive potential TVs are the Samsung KS8000 and the Vizio P-series. Since digital foundry is using a pretty inexpensive Pana LCD for their tests this unit might also be a good consideration (If I am not utterly mistaken it has an 8bit panel though).
Your linked TV does not support "real" HDR (at least if it is exactly the same model as in Germany).
