Decca Classical Reissues Mastered at Abbey Road? Copies of digital files? Or REAL Reissue?

There are a number of Decca classical reissues on vinyl that are showing up on Amazon such as this one:  https://www.amazon.com/gp/product/B00XZKT30A/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1  

My question is this:  Is this record the speakers corner reissue which is guaranteed to have been mastered from the original decca analogue tape?  OR is this Decca/Universal taking the digital file of this historic recording and just transferring it to vinyl.  Earlier speakers corners reissues of other records that I have had very little on the back of the jacket to identify it as a reissue at all.  THIS one has a back jacket that mentions only Decca and remastering at the Abbey Road studios.  Obviously the ONLY reason to buy a reissue of an original Decca/London recording from the pre-1970 era is to get a REISSUE of the actual record, not a digital transfer onto vinyl.  NOW I'm usually the last one to be clued into this whole thing, and I know this has been an issue in the past more generally speaking.  BUT my question is, is THIS record, and all the ones like it that have begun to appear as being sourced from Decca Classics just a copy of the digital file, or is an actual analog recording made from a lacquer which was made from the original analogue tape?  Anyone?
