Enjoying my Panasonic UB9000 with my JVC RS1000. I originally purchased the UB820 but decided the additional benefits from the UB9000 paired with my JVC projector were worth the upgrade...not too mention the build quality improvements. I used the manufacturer white sheet recommended settings for the JVC projector and Pani UB9000 and found improved image over the UB820 which lacks those specialized settings for JVC NX/RS projectors. Although improvements are stated as being even better if paired with the higher end models NX7/NX9. I first setup the UB9000 as I had done on the UB820. Then i setup as advised on the white sheet as advised by JVC and Pani. I noticed increased detail in shadows and in brighter scenes...such as cloud outlines. Also I feel like facial or skin tones are more defined. I currently use the UB820 on a 55 inch tv. I have had no issue streaming 4K or atmos. I use a fiber cable for my projector and certified 4K hdmi (the UB820) for my tv. I run it through a Denon X8500H to my projector and direct to my tv (the UB820). I have owned the UN9000 for about a month now and am really impressed. I hope but have no idea if Panasonic will add more standard apps like Vudu, MoviesAnywhere, Apple TV +, Disney +.
