Everything here is a great thought. But as @Soundmixer said there's too many other variables to say for sure.But that is what they are doing; boosting lower-level content that is still there. Not all Blu-rays exhibit this. My question is, what are the reasons why it would be reduced so much in level for the Blu-ray compared to the theatrical version?
My own suspicion would be that the Atmos HE mix was done on a different stage, perhaps even by a different mixer, and they felt they needed to reduce that content intentionally for some reason or other.
Just to speculate for what it's worth, most of the small rooms I've mixed in aren't massively acoustically treated down to those frequencies, so maybe the 20-30Hz content came out overwhelming for them and they reduced it. Who knows. Yet another possibility is they didn't feel like it brought much to the party but was using up modulation width (level) on the recording and reduced it to increase headroom / avoid pushing the limiter.
I would say though, my own experience of moving from the large stage mix down to the HE mix is that when you engage bass management, you quite often get more bass than you had before. Sometimes it's not a lot more. Sometimes it's actually good, and it's often the first time we get to hear what we had below about 40Hz on the LCR. But sometimes it's quite noticeable and needs addressing - which does tie in with my original rant (ahem, observation)
Oh, so I guess, maybe the Atmos HE mix was done to make it sound more like how it did in the cinema space without that low end content (perhaps by the original mixer who was used to that), and the person/team who did the DTS just enjoyed the extra LF extension. More speculation.
