There is a 'software-only' version of Dolby Vision that has been developed but this is mainly intended for use with electronic devices such as mobile phones etc... This is watered-down and hence is NOT the same as 'full'/'proper' Dolby Vision which does indeed require specific hardware, including DV decoder and display management technology.
But some products have already had said hardware included to pre-empt the future addition of DV via simple firmware update, such as the OPPO 203 and 205 Blu-Ray players, and IIRC the SONY ZD9/Z9D TVs.
That said, it would be vey easy for JVC to make the neccesary hardware addition/modification with respect to the Z1/RS4500 and simply roll this out as the 2018 model, in precisely the same manner that the RS/X series projectors have undergone tweaking on pretty much an annual basis
Either way I think it's fair to say that, given it's JVC we are talking about here, if DV is worth adding to HT projectors, then JVC will add it. And we agree with Adidino in that we don't see anything that would prevent JVC being able to add it to the RS4500/Z1 via simple hardware modification plus firmware upgrade
Whether the display happens to be a TV or projector, this will fortunately be pretty much irrelevant, because uniquely with DV the video content will be adapted via the DV decoder and display management technology according to the properties of the particular display such that the DV video content is displayed optimally on each and every video display device, irrespective of whether it is a TV or projector.
Additionally, via use of DV's dynamic metadata feature the HDR video grading/settings are varied frame-by-frame. This has the huge advantage and upgrade over and above existing consumer HDR video formats, including HDR10 and UltraHD Premium, where with all of these the HDR video grading/settings are static, meaning that one singular set of settings are used for the whole video/movie. Whereas, with DV not only can different scenes have a completely different set of HDR video grading/settings (which is kind of important when there is such a massive variance between video that is filmed in the daytime, nightime, outdoors, indoors, etc.) but DV can also do this on an individual frame basis, where quite literally every single frame can have its own settings such that each and every frame yields optimal HDR video performance.
There is currently a massive variance with respect to the grading of consumer HDR video content, where the designated white clipping point ranges considerably from circa 1,000 nits to 8,000+ nits, but where display devices currently have no ability to deal with or handle such variability; meaning that there will be a significant variance in HDR performance across the various consumer HDR titles. Where the only way of dealing with this currently is to use an external video processor, such as the Lumagen Radiance Pro, and use this to regrade all HDR video content to the same nits clipping point and that which matches the capabilities and specifications of the particular video display device, whether it be a TV or projector. However, this is expensive and requires a learning curve or contracting the services of an AV installer to setup. However, DV essentially does this itself (whereas the existing HDR formats do not) thereby negating the need for such additional equipment, and ensuring that the HDR video content is displayed to its best ability with respect to whatever video display device, without any such additional expense or complication necessary.
For these reasons we very much hope that DV will become the industry standard that is used for all consumer HDR and both HDR10 and UltraHD Premium fizzle out and fall by the wayside.
