No. None whatsoever in and of itself, when mixed into a "Flat" base. One can mix it into a "Satin" to acquire a bit of sheen, but that sort of thing was reserved for PJs of lessor Lumens than yours.
Nope....you must look at SS as being a simple, roll-able paint, mode at least as good as the quality of the base it's mixed with. It is a virtually neutral Gray of a moderately dark shade tat both assists (via attenuation) the appearance having deeper blacks, while also adding some degree of ambient light resistance.
The latter especially if one has the Lumens to punch a bright image onto the Gray SS surface.
There are other choices, and some are not complex, but anything really "contrasty" w/Gain is going to require spraying because you can only get such gain with the addition of enough Reflective particles to catch and reflect the higher energy brighter content back at a degree higher than the less energetic darker content. Those particles are randomly distributed when sprayed, but rolling almost always will lay them all out vertically to the Len's face, creating excessive, mirror-like sheen.
We have been "focused" on achieving the maximum amount of gain possible with the darkest surfaces....and we've come far. Some things...like the necessity of spraying remain constant though.
When PJs with 1,000,000:1 dynamic contrast and 3500 lumens are commonplace, still, a Gray painted surface will be desirable, always delivering ambient light resistance for pennies on the Mfg Screen dollar. That day is not really far off. Already there exists a BenQ 1080p (890) w/4000 lumens and 50,000:1 DLP dynamic contrast (...that any DLP advocate will tell you 'is to die for'....) and it's average "street price" is $2495.00 (I've seen it as low as $1900.
Yeah...it's louder than desirable (34 db), but in Econo (31 db) w/3000 hr Bulb, it's still pumping 3200 ansi lumens and your getting every bit of that 50,000:1 CR when it's available.
So you see, by your painting a SS screen, you taking a wise step (..if one wants to take baby steps ;D ) that gives you a Gray surface just dark enough to matter and be ideal for a 2000 lumen PJ, and doing it cheaply enough that upgrading again to a lighter gray w/Gain will still make sense. Both performance & fiscal-wise.
....or, do what PB above suggests (...btw, I was hunt-&-peckin' this out before he started...) and haul up, get just the few (2) extra ingredients required for RS-MaxxMudd -LL , and experience Low Lamp, high contrast, performance that still retains some ambient light performance. That solution is also roll-able, the only high performance +gain mix that is.
