Virtually all consumer 4K content so far on Blu-ray UHD uses HDR, but there are some exceptions. Additionally, so far, most Netfix streaming (can’t speak for other streaming) 4K content does not support HDR.
My primary focus is on 4K content with HDR and expanded color space, which is to say, these days, is primarily content on 4K Blu-ray UHD discs.
But I am not routinely checking out 4K streaming on Netflix, relying primarily on Blacklist for my analysis. Unfortunately, after I sent the JVC back, I realized I had never taken photos form Blacklist on Netflix, or have misplaced them. (probably forgot)!
It was a pretty great experience. With the HDR adjusted to provide respectable brightness (read Eric’s comments on the calibration pages), it was certainly the best viewing experience since the Sony VW385ES (native 4K). As noted skin tones were near excellent post calibration, but the RS440U has a little more trouble trying to get to P3, than more expensive laser projectors. Still, I was never unhappy. Like predecessors to this model, once again, it rocks, and in this case, it rocks on high quality 4K content. If, as Eric points out, technically his HDR mode, with P3 calibration proved a little less accurate than his 1080p/REC 709, but then its doing a really good job with great color space, as opposed to excellent with an inferior color space (REC 709). That certainly earns JVC a pass.
A quick note if comparing against the Epson 5040UB. Eric indicates that the Epson has the slight edge when it comes to tackling P3 color space. Not enough to matter. The more important aspect today is preventing dimness in the mid-lower ranges as HDR tries to stretch out the dynamic range.
Until Epson’s last firmware upgrade, this would have been no contest, as the Epson started out seeming dim in those mid and lower ranges, when first released. Even, the last calibration settings we posted on the Epson with custom gamma, etc. it’s still was a little dim. The most recent firmware version, though, is close enough with regular gammas, and that can be customized, . Either way, reasonably close to the JVC in this regard, based on direct comparisons.
(The two projectors features and capabilities wise are very similar.)
