That does seem like a strange "room correction". It assumes that rooms are bright and have linearly poor bass response, which is a very strange assumption. Bass issues usually peak or drop off at irregular intervals dependent on the room characteristics (e.g., dimensions). The calibrated mic is a good idea since it should pick up the uneven responses, but the 1db/octave linear boost of bass does not seem to be a room correction factor; it seems to be an equipment correction or personal preference adjustment.
