The same exact rules apply as with Blu-ray; it depends on the studio's decision. I have numerous DVD-Audio discs where the studio claims in the liner notes that the output of their work flow was transferred directly to disc without down-sampling. Lossless compression is used (and uncompressed delivery is also possible), so the capability is obviously there.
By the way, since this seems to be a source of confusion based on what was posted earlier, DTS-HD MA is merely a lossless compression codec (with advanced metadata capabilities). It losslessly compresses what the studio feeds it. DTS doesn't tell the studio what to feed the codec. The studio could very well encode a 48/16 track with the codec after it was first down-sampled/dithered from 96/24.
Not true. The studio HAS to feed the lossless codec the studio master AS-IS as a REQUIREMENT for using DTS-HD MA. Same for Dolby TrueHD. I tried to explain that before.
So yes you will be getting the studio master with blu-ray.
If you feel the studio master is not as high resolution as it can be, thats a different issue.

just for a second here... since none of us have even brought up the "bigger issue" with what you want... let's say you do get what you want...
let's say that the "studio master" is quantized at greater than 192 (which, as we've already established, is available today)...
what, pray tell, do you plan to play this back on?
merely encoding something at a higher rate in no way means that the dac/dsp would actually handle it... merely being on bluray in no way means that the dac/dsp would actually handle it...
It's just a codec. They don't have to use the full-resolution mastering format, they can use a slightly lower res finish and then just put that on the disc losslessly.
You can't put 48-bit or 32-bit floating point on a disc, and that's what is generally under the hood of most modern audio mixing/mastering software. It all gets down-res'd to 16 or 24bit usually for output.
So your whole demand of having "exactly what the master is bit-for-bit" is, as I have been explaining to you this whole time, is a grotesquely ignorant oversimplification. Which part of the master do you want bit-for-bit identical? Because there can be points in the mastering chain which are quite a bit higher resolution than anything that is conveyed on Blu-Ray, DVD-A, or SACD, but that isn't a meaningful issue because they are interim processing steps, as I already explained. You don't need that kind of precision for finishing or delivery.
Or if the Blu-ray audio track is upsampled from a lower-resolution digital source. This happens occasionally with video; it'd be naive to assume that it doesn't also happen occasionally with the audio. Possibly more frequently than we'd expect -- and probably not audible anyway.
Yes, if you're using the term "studio master" the way you've been using it. But then, CD is also bit-for-bit identical with its studio master too, in that sense.
That's what "no compression" and "lossless compression" mean.

I am an illegal alien you numbnuts. That's why I'm lying to you about Blu-ray discs. I snuck into this country decades ago, went to school and college and became an audio/video professional because I knew that at some point in the future I could fool some unsuspecting troll about the technical aspects of redbook compact discs.
Clearly my disguise was insufficient. I'll have to up my mission a notch to seeding some muslim-terror-anchor-babies.
Did you ever stop to wonder why surround-sound started out with 5 main channels??
Well... it's because of the FIVE PILLARS OF ISLAM! See how scheming we are!? You have just SURROUNDED yourselves in an audio-jihad! And not one of you even ever guessed it!
Let me know when you get your GED.
(This is a particularly amusing troll.)
