Formats like DVD audio and other high-res formats set strict limits for minimum dynamic range, overall loudness and other mastering parameters.
No they don't. There are no such limits either technically or in the licenses. What there is, sometimes, is a desire from the seller of the high-res format media to cater to a different audience, and therefore use a different set of mastering parameters.
There is nothing stopping anyone from making just as compressed a DVD audio as a CD. Or a 24 bit FLAC, or whatever. It's all just PCM. And not even SACD/DSD/DSF is immune to this, although the technical details differ.
