Ok my listening room is absolutely cr*p but I've adopted and due to limitations i sit close to a backwall I've adopted to that to probably.Yes, also the listening impression can be different as humans automatically adapt to the room acoustics in few minutes when they are in a room which probably won't happen though a recording. About equalised binaural recordings, like you say they are unfortunately rare, but very few try to make some, like for example Oluv but even there it is still a work in progress.
