Yes, that's true. I'm not sure why they took away the red filter over the display. Perhaps it was done to match their newer products like the BeoSound 4. The red display makes better sense because it is easier on the eyes in a dimly lit room (like when watching movies).
I'm not sure if this can be done, but you may be able to have someone add a red filter between the LED and the contrast screen. Most LED displays like the one on the BeoSound 9000 and the old BeoVision 7-40 are white with a thin, plastic red film laid over it. Simply add the red filter yourself, and the "problem" is solved.
