Most digital recordings of classical music use no compression or very little. All-digital (DDD) recordings do not use noise reduction save those instances where there is some ambient noise (like air conditioning) that needs to be reduced in level. A lot of the digital transfers of older analog recordings use various forms of noise reduction. Results can be good or bad depending on the skill of the engineer remastering those recordings. A lot of the DGG CD reissues of Herbert von Karajan's recordings from the 1970s have better balances than the LP originals. Warner Classics has done some remarkable work with classic recordings from the 1930s. DGGs "The Originals" series of CD reissues have been very good.You are right and wrong. We CAN measure everything and digitization DOES NOT lose anything.
You are right that digital does not sound as good as classic vinyls. That’s because once the audio is digitized, humans have a hard time *not* choosing to adjust levels, add compression, or reduce noise. At that point, you are hearing the decisions of the person manipulating the recording.
The best thing to do if you have your own premium setup is to make your own recordings. You will see that you can capture all the nuances. Why digital isn’t mastered that way is a whole different questions.
