That would be a pain for me, with my cable installed through the attic and the wall. I just want to know if the picture upgrade is really worth it. It's a lot of trouble for a picture that is not even true 4K. My screen is pretty large, 160" 2:35. I'm wondering if HDR would even work well at that size. The one reason I'm thinking about it the most is the fact that some Blu Rays don't include the Atmos track, it's only on the 4K version. So, is it worth the trouble?
This is a tough call, and obviously quite subjective.
I also have the RS400, with a 160" 2.35:1 screen. Mine is 1.3 gain, which helps - what is yours? My throw is about 18 feet. I have done black velvet treatment around the screen, with a black rug in front, but my walls and ceiling are not black.
I have done the JVC Autocalibration, and used Arve's Software to generate a custom curve for my particular situation. Overall, the result is quite good, but I'll have to be honest and say that overall the improvement, to my eye, is not a night and day change. I mean, many regular Blu-rays look so dang good, it's hard to improve on it.
If someone has the RS600, a smaller and/or higher gain screen, shorter throw distance, and a bat cave room, then there would likely be a more noticeable degree of improvement. But with the RS400, and larger screen, and in my situation, a decent room, but by no means a bat cave, it's not a huge improvement.
And the improvement will be more evident in some movies more than others, and some scenes more than others.
As you point out, sometimes the 4k/HDR version is the only one with the Atmos track, and that will provide a side-benefit, so to speak.
If your goal is to get the absolute best out of your system, then 4k/HDR is the way to do it. But I personally think it would be unrealistic to think you'll be completely blown away by what you could get beyond a well-made regular Blu-ray.
Don't know if this helps, but there it is!
