I have been having issues with the ATV 4K consistently delivering HDR. What HTRs have you had success with?

I have been using the Marantz NR1508 and they should work, spec wise, but they have been a bit hit and miss. I have used both LG and Samsung TVs with the same issues. I have found if I plug the TV directly into the TV it works but when I go through the HTR I have issues. 4K is not the issue just HDR, 4K has worked fine. I am primarily doing multi-use rooms and living rooms not big home theaters, so price is a concern.
