Unless I missed it, I haven't yet seen any mention of timing compensations based on IAT. I haven't yet looked at the compensation tables for a BRZ, but I know on other platforms there are timing compensations for all sorts of things... water temp, IAT, load, etc. What I remember from the IAT compensations was that timing was most advanced (optimized) in "safe" IAT ranges, something like 30-70 degrees. If it's too hot, timing will be pulled, and if it's too cold, timing will be pulled. This is in addition to whatever timing may be pulled due to perceived knock events. Anything above or below that, timing started being pulled. So in addition to air density that would have something to do with it.
It would be great if someone who's seen the tables can confirm (or deny).
