Before CD’s or DSD’s or LPs are cut a final master is made. This final master may go back to a previous 2 track master or to multi-track originals.
Re-mastering means that a new final master was made and that the new mastering engineer has re-thought something. EQ, compression or the down mix from the original multi-track are quite common.
Really depends on who is doing the remaster and how good the material was they had to start with.
It was also true that some DSD's were remastered compared to the CD's, and they had different frequency profiles and compression profiles, leading to the obvious conclusion they sounded different.
