I just finished doing a similar test. I have a friend who is buying a Grayhawk, he brought over the sample Stewart sent him.
My screen has already been painted "veil" grey, which is a moderately dark gray. My screen is painter's canvas. I also compared it to a sample of the original white canvas material taped on the screen and a sample of gray painted canvas with pearlescent paint on top.
I have an uncalibrated G1000, and my screen is 114" wide.
My grey is a good "two shades" darker than the GrayHawk. They GrayHawk is actually a gray rubber material with silver/pearlescent-like paint "splattered" lightly on top. I would say that it has 30% splatter coverage, with 70% grey showing.
My observations are as follows:
Unpainted white canvas
Overall brightness: plenty bright
Saturation: lighter colors (yellows especially), are very vibrant and saturated. Darker colors looked less saturated.
Blacks: are fairly washed out.
Contrast: Lacks "depth".
Brightness: not as bright as the white, but brighter than my gray.
Saturation: Lighter colors were more vibrant than my grey still lacking saturation compared to white. Darker colors (especially dark blue and red) had more saturation.
Blacks: The biggest surprise was the GrayHawk's blacks were nearly identical to the white screen. The more we looked at it the more we couldn't believe our eyes. Using my "highly calibrated" eye I would say that the GrayHawk's blacks were only about a "half shade" darker than the white. Very unexpected.
Contrast: better than white, but not dramatically. Also lacking in "depth".
Gray painted canvas("veil" from glidden from home depo)
Brightness: fairly dark overall, once my eyes adjust, it becomes very tolerable.
Saturation: light colors (especially yellows) look "dingy" and unsaturated (example: walls of Bruce Willis' apartment in Fifth Element). Dark colors look very saturated.
Blacks: Amazing!! Jet black, like looking into a black hole.
Contrast: Once your eyes adjust to the dim picture, the contrast looks excellent. When watching bright HDTV scenes, I feel like I could get out of my couch and walk into the movie.
Canvas painted "veil" gray then painted with pearlescent FX paint
Brightness: Somewhere between GrayHawk and veil.
Saturation: same as veil
Blacks: blacker than GrayHawk, but not as black as "Veil"
Contrast: VERY good. Dark blacks, and striking highlights.
Hotspotting: severe hotspotting problems. To the point of being unusable.
Given all of the options, I would say that I prefer my current setup, Veil grey painted on canvas - no pearlescent. (actually I premixed a bunch of perlescent into my paint, but they gray overwhelmed the pearlescent eliminated any positive effects). It will be interesting to see how the overall brightness improves with my Panamorph when (if?) it shows up.
Advice to Stewart: make your base gray darker, you have an impressive coating, but the gray is too light (for me).
D-ILA, HTPC, HDTV, Panamorph(?)
