Texture is a old topic that has lost none of it's relevency it seems. And most people often misconstrue it's value as well as it's detrimental aspects.
Texture on any Mfg screen is there to help avoid the screen's tendency to Hot spot. Nothing else. Since many Mfg Screens have the goal of producing a bright vibrant image, the use of particularly reflective surfaces demand that texture be present. It's no wonder that the brightest of screens always have the most texture as well.
Lamenates usually have virtually no texture, so the finish being as flat as possible is very important.
Is texture desirable? ONLY if one needs it to mitigate sheen. Otherwise it will, and always does compromise image quality, especially if you are pushing "Viewing to Screen width" distances to a closer parity.
With a good 'ol Z4 and a truely flat hued, textureless surface, you can get down to as low as 1.2 to 1.0 x width to distance, to acheive a truely immersive experience. D-ILAs', many 720p DLPs, the newer Pannys', and of course any new 1080p PJ will seldom "add' pixelation. But presented with texture, any of the aforementioned with any tendency to show any SDE or Pixel structure will have that tendency amplified by texture.
Choose a ready made surface or painted application that does not hot spot or fail to distribute light evenly out to the edges, and you'll never be a victim of eye fatigue. Or sit back way far and enjoy your "Big Screen' in smaller circumstances. And go "Kiss your Sister", for that is what making a big screen look smaller via increasing the viewing distance out of necessity is really all about.
That is most deffinately a case of backwards thinking to me, and not in keeping with the improvements in PJ quality, and available signal sources.
Lastly, texture often demands that the eye constantly re-focus, and it highlights any/every degree of noise or pixelation. All of that, as well as too much light reflecting back directly to the eyes creates a less than desirable effect on the eyes, one that is a leading cause of eye strain, and exactly why for so many years we have all been stuck with having to restrain our viewing distances to 1.8x to as much as 2.2 x D to W.
For many, texture is an unavoidable consequence of application of materials or the material's existing surface. To introduce textue to mitigate undesirable aspects of something else is counterproductive at best. better to solve the first issue instead of lumping on another to deal with. If a surface comes with a slight texture, and a hue condusive to recieving an image, it can be construed as being acceptable, but certainly NOT ideal.
"Glass Smooth" & Flat Hued is the real goal. Introduction of the appropriate amount of metallics in a controlled fashion, within an essentially Flat hued substance can increase gain and reflectivity, but taken too far, will introduce additional issues.
It's all about balance, and without balance, at best one can expect is a "Humpty Dumpty" kind of approach. Often, you must pick up the pieces of your work & ideas and start all over.
