I am still using THX Select2 Cinema (with Re-Eq Off) but what exactly gets shut off?

Audyssey Dynamic Equalization and THX Loudness Plus pretty much do the same thing. According to Audysey, their Dynamic Eq is more advanced.

I really do not know the exact answer to your question. My receiver does not have THX and I am not familiar with your Onkyo receiver. It may be a good idea to consult the manual and/or send an email to Onkyo or Audyssey.

The following is from a post by Chris Kyriakakis of Audyssey

Audyssey MultEQ creates room correction filters to two specific target curves. One is the Audyssey Reference curve that has a slight roll off in the high frequencies above 10 kHz that has to do with the translation required from a large movie theater to a smaller home listening room. The other is Flat that has no roll off. Some AVR makers decide to give the user a manual choice and others, like Onkyo, make the switch automatically.

Re-EQ is not an Onkyo function, it is part of THX. We recommend using the Flat room correction curve so that the intent of THX Re-EQ is preserved. Onkyo allows you to switch Re-EQ on and off separately from the other THX functions and so you could listen to Audyssey Flat if you turn off Re-EQ.

There is no interaction between the Re-EQ button and Audyssey. If you are in THX mode then you are listening to Audyssey Flat regardless of whether you have Re-EQ engaged. Of course, if you do have it engaged it applies a high frequency adjustment that takes you away from Flat. I recommend using Re-EQ with Audyssey Flat for movie listening.

There is no way to have Audyssey Flat in Onkyo products without having the THX mode engaged.

In Onkyo receivers with THX, if you turn on Re-EQ and you are not in THX mode, then you will be using the Audyssey Reference curve plus Re-EQ.
