Just downloaded the files and compared them (before looking at the spoiler for what that's worth.) and I couldn't tell the difference at all.

You don't have to use short lowpass filters, because anyone can do resampling from 44.1 to 96 kHz during playback, for example with the SoX plugin for fb2k. (I used the filter used in SoX for processing the files.)
Is the white noise shaped to look like the original, unfiltered 96 kHz signal, or is it generated entirely from the brick wall filtered version ? In the latter case, it is surprising how well the original content is "guessed" by the algorithm.
I was close!
You're choosing between a full range high bitrate master and a regular CD with noise above the audible spectrum. I think that pretty much shows that you don't need those super audible frequencies or high bitrates.
