I guess I just lucked out with my first 4K projector, since JVC's current true 4K lamp-based projectors are pretty much plug and play, once you have this fall's firmware in place and set them to frame-by-frame or scene-by-scene Dynamic Tone Mapping for HDR, which relies not on the metadata coming with the image but on the content of the image itself to do the tone mapping, which is, in essence "contrast scaling."
You don't need the tone mapping done by the Panasonic players or by MadVR or Lumagen - unless you just love to tweak.
The only tweak I've made, since I have a big, low gain (0.93) screen, is that on the projector's DTM setup screen I selected "High" instead of Auto, Medium, or Low.
That makes the image a bit brighter.
These days, 0.93 gain is considered low - most of the folks in the forum on those projectors use 1.3 gain screens, which concentrate the light into a narrower viewing area, and make the choice of 3D glasses more critical, because those screens preserve the projector's polarization - and some glasses are polarized horizontally and some vertically.
JVC used to be an outlier, using the opposite polarization from everyone else, but with these models they fell into line - so the glasses that worked with the older JVCs will yield a dimmer image. With my painted screen this isn't an issue, as my screen disperses the polarization, so both orientations work equally well.
