Without more details, we don't know the source of the problem. The key thing is to understand whether it was on the original tapes or not. These are historical artifacts and are what they are. But if there is no signal on the original then there is little excuse for adding it in the remastering. If the remastering engineers were first rate, they are probably aware of the situation. I would be surprised if the original masters had 28 kHz noise on them, but not if it was at 15.7 kHz. The masters were made before switching power supplies came into use.
It is also possible that residual (harmonics of) the bias oscillator beat with the sampling rate used. If they produced such a loud artifact this indicates something wrong with the digitization process.
If the original digitization of the archive tapes doesn't have the artifact then one can only conclude that the remastering people were incompetent. But we don't know. They probably do if the engineers were first rate.
But note, some of the engineers working on remastering of historic classical music albums are definitely not first rate. This is obvious by listening to the product. I would be suspicious if the masters were captured at 96/24 instead of 192/24, as it indicates that the engineers did not have audiophile pretensions.
