What is the native rate for the chip’s delta-sigma modulation? 1-bit, 2.8MHz? My guess is that sample rates with the greater processing overhead to decimate & oversample, or Fourier transform, or whatever needs to happen computationally to get them to the native rate would result in higher power consumption.

I think it's quite a bit higher than that, actually.
It's 48/96/192/384 x 64/128/256/512/1024 and
44.1/88.2/176.4/352.4 x 64/128/256/512/1024
I think default target is to hit 45.1584/49.1520MHz (ie. 48 * 1024 = 49,152)
There might be an alternate mode that makes the target half (22.579MHz and 24.576MHz)
That's the idea I get from the datasheet, though I'm not 100%
