The JZ1000's are great TV's. The color reproduction is outstanding even on factory calibration. HDMI 2.1 capable but not full spec since it can't do Dolby Vision on 4k 120Hz but can do HDR10 on 4k 120Hz. In terms of HDR standards, this Panny has a complete set of HLG, HDR10, HDR10+, HDR10+ Adaptive and Dolby Vision.
The only cons for this TV really is the OS.
I hear there are about a handful left each of the 65" and the 55", priced at 89k and 45k, respectively. The 55" is a great deal, imho.
