I can't commnet on your set up and results but to be more specific about mine, all walls are dark gray / black. The ceiling / floor are also very dark. THe front and screen wall are flat black painted walls covered with black GOM and Black innsulshield.
When the film starts, the walls, etc. blend into the black abyss up front.
Only the screen is lit, you cannot even make out the masking. When I remove the masking and project images (as I demostrated to 20 or so AVSers at my meet), I showed that when the DILA gray bars disappear, the image jumps out from the deep black periphery. It is quite impacting on the CR. Conversely, the gray DILA bars hurt the picture (without masking).
Without trying to disprove what Darin sees ( I do believe Darin), Darin may have some interactions from the white walls and hi powered screen but it is hard to imagine masking hurting the picture. However, there is lot of relected light around the room that may be further graying his blacks. However, as I thought about his findings, things became clearer. As Darin says, his front wall is a simlilar gray as the gray DILA bars. So both elements blend in as one homogenous gray. The fact that both grays match is positive. If the masking is darker than the area around the screen, I can see how the two different colors (black velvet masking and gray DILA bars) with a picture on the screen may create a problem. My front wall (masking and front / screen wall) are absolute, deep black. Homogenous all around. Therefore, that is why things look so nice to me with the masking. The black around my screen, gives the perception of the DILA gray blacks as black blacks. The black periphery lends to this positive perception. The gray periphery, I hypothesize around Darin's screen, helps to further enhance the DILA's gray blacks.
Therefore, depending on what the walls, celing, screen area are colored (light versus dark), you may or may not get the maximal impact out of a black masked screen - or it may hurt your image.
