The use of a Light Gray Moleskin Spandex directly against the rear side of the Screen is one viable option....however if indeed the material lies directly against the wall, use that old standby SS is also very acceptable.
The telling issue left unaddressed...is in fact the Spandex "Touching" the wall. Loss of light through absorption being the cause of a loss of sharpness, that would indicate that the energy of the light that passes through is dissipated too much to be of any effect. Either distance from, or the color / absorbancy of the wall paint is the cause.
Unless you can "thicken" the material and reduce the total amount of absorption loss, things won't change enough to matter.
Some suggest Black as a backing, but all the same still applies. It would have to lie against the front surface's rear side, and be wholly impenetrable, or two things will happen.
- Any light reaching the Black layer will be absorbed.
- All light that passes through the top layer is simply wasted...gone.
- The presence of the Black will shift the color of the White Spandex toward a deeper shade of Gray than should a light Gray or Silver. That means attenuating light more severely.
I see considerable light below the screen, which is either "overspill" or light reflecting off the wall surface behind the screen. If the latter, then for certain the screen stands off the wall at least 1" or more. Taking your description at face value that doers not seem to be the case, so my final suggestion is to get a sheet of either Dark or Light Silver Moleskin Spandex and apply it loosely against the rear of the existing surface. Don't use Velcro, as it's bound to create at least some degree of stand-off. Rater use some flat, 1/4" x 2" wide Lattice and laying the second layer against the rear side and over the Trim, first attach the top edge across the length by using short screws through the Lattice / Spandex, then "lightly streching it across the bottom edge, screw it into place.
You only want to stretch it barely enough that is smooths out and does not produce any transfer of it's own texture against the front material.
