In many cases I'd agree, but in this case I think it's perfectly fine (and there's no other way) since Apple is just a distributor for other people's recordings.
I think it's pretty clear Apple is making "192 kHz/24-bit Hi-Res Lossless" distribution and listening available, but obviously it's up to labels and artists to supply actual recordings at that level. And many can't, simply because it wasn't mastered at that level, or wasn't even recorded at it.
It is often a way for companies (or headlines) to seem to be claiming something without actually committing to anything.
