It is almost as if the light is somehow bouncing of the filter (possibly being reflected at an ange to the screen by an adjacent patio door). This makes me wonder if the intra scene contrast is being erroded by this effect occuring with larger blocks of light colours 'ghosting' onto darker parts of the image. My light coloured room doesn't help, but that is soon to be fixed with a dark 'chocolate' screen wall and 'Mocha' coloured side walls.
I do wonder how much improvement is possible with a darker room, but a 'batcave' is out of the question and an ND4 filter will probably make the image so dim as to be unwatchable. Even when I turn off the PJ the screen is clearly visible, so that is the best 'black' I could theoretically get with a 'perfect' PJ in my existing room.
