You are absolutely right Joe that with LCoS type projectors such as SONY's SXRD projectors and JVC's D-ILA projectors, both of which are LCoS, the lamp-based projectors are at a disadvantage in this regard verus the laser models. The reason behind this is that the lamp light sources in combination with LCoS in those situations produces a phenomenon called micro-flicker. And this is not present with the laser projectors. It is also, for whatever reason, not present with the SIM2 HDR DUO PLUS either
I think this partly explains why in the blind tests we carried out that everyone believed that they were actually viewing a 4K laser projector
Also, there is no singular blue laser through yellow phosphor type home theater projector that comes even close to achieving the color performance of the HDR DUO PLUS. Sorry!

Firstly, 8K panels are not emerging, they've been out for years, in the professional market
Secondly, it boils down to overall video performance. And specifically what most influences video image quality, wherein scientifically speaking resolution is about 4th of 5th in the rank of importance. Now I am not saying resolution is not important. It most certainly is; it is simply that there are other aspects that influence good video image quality to a greater degree, primarily due to not hitting the limits of HVP.
The fact of the matter is that we have is most situations hit the limit of HVP with 4K resolution, meaning that in almost all circumstances 8K resolution is a marketing gimmick and nothing more. You would need a colossal sized screen and/or ridiculously close viewing distance in order for many people to be able to tell the difference. Something which this chart illustrates:
Where in fact in many home theaters the benefits of having 4K resolution over HD 1080p will not actually be being realized, especially when it comes to rows of seats behind the front row.
However, what you CAN perceive from any and all seating positions is all of: Black levels; Contrast; Dynamic Range; Color Accuracy, Depth, and Saturation; Gamut Coverage; Gamma; HDR Tone-Mapping; and Image Luminance... to name just a few.
Aside from the Christie, name me one single 4K laser projector that scores a near perfect high score in every single one of these categories without exception. You can't because none currently exist. Wherein, the fact of the matter is that a projector such as the HDR DUO PLUS which achieves precisely this, but which is HD 1080p resolution, will deliver superior overall video performance as compared with another projector which is 4K resolution but does not.
So like I said, it boils down to overall video performance.
I also personally think that when you have suboptimal performance with respect to these other aspects, the perceived influence on the video image of resolution is that much greater. But when these are all maxed out the perceived influence on the video image of resolution is actually less. The typically higher MTF of DLP versus LCoS probably also factors into the equation
