I have said this before. The light bleed from the vents is not affecting the image contrast. Way more bounce is created from the light off the screen and the surrounding areas. Unless you literally have dark walls, floor, ceiling, furniture, and no reflective items in the room. And even then, the light bleed from the HD20 is so minimal it does not affect the image.
Here is an easy test, you temporarily block the light bleed using some cardboard or other material while you have a movie playing. I have done this test and can not see any difference on the screen.
I have ultra dark walls and furniture. But my ceiling is flat tan. Though my ceiling is also pretty far from my screen and if my ceiling was affecting my image, I would see some form of wash out that is greater at the top. And I don't.
Also, the smaller the room, the more important it is that you have dark colored walls, ceiling, and furniture.
Do the test and be satisfied; then look at the rest of the environment.
