HDR Tone Mapping

It's not clear if this technology can be applied to other Benq projectors via an update, or it's limited to the models capable of covering WCG. Maybe @sage11x
has more insight.
This question could be asked of other models, for instance is the tone mapper the same on the Epson HC3800 and HC4010, with the 3800 covering only a small amount of the WCG?
BenQ’s HDR pro is a really interesting solution. Talking strictly technically: projectors aren’t really capable of HDR. The general practice so far with HDR on projectors has been to essentially convert it to something resembling SDR while retaining as much detail as you can. As I mentioned above in my comment about the UB820– at the end of the day you have an HDR image that doesn’t look all that different from an SDR image is the goal.
BenQ’s solution is different. It attempts to retain some of that HDR ‘effect’ by controlling saturation and contrast. You might even call it a simulation of HDR that takes into account the limitations of your typical projector. Critics will point out that this isn’t maybe the most accurate way to display HDR content but I would argue that there really isn’t an accurate way to do HDR on a projector without it looking dull. That (along with clipping) was one of the big problems with HDR on those earlier models. HDR on the BenQ looks, for lack of a better phrase, ‘more HDR’ and it does a fantastic job at sort of hiding some of DLP’s limitations when it comes to black levels and contrast compared to pricier options.
It’s certainly gone over well. Critics from Chris Eberle to Art Feierman have praised the BenQ projectors for their HDR image quality even when placed against competition that handily outgun them in terms of native contrast and black level.
JVC’s solution is a whole other thing. From how I understand it, JVC is essentially attempting to add back in the tone and gamut mapping metadata that HDR10 omits on the playback side— I would actually go as far as to say they are trying to ‘fix’ HDR10 by making it behave more like HDR10 plus or dolby vision by having scene by scene levels of control over the image. No idea how well it works...
What to do if you find yourself stuck with no hope of rescue:
Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems to be more likely, consider yourself lucky that it won't be troubling you much longer...
