I love roon, and while I’m mostly a jazz fan, I do love classical too. Let’s try a “for instance” with roon, with which I subscribe to Tidal, maybe you’ll get a better feel for it.
A few Saturday’s ago I was listening to my favorite local Classical station; WNED FM 94.5 (highly recommended, you can listen online).

The NY Philharmonic was on and they featured; Fantasia On A Theme By Thomas Tallis. I loved it and “Shazam’d“ it.
The next day I tried to find it in roon, and to be honest, it wasn’t as easy as searching for any given Jazz track. I eventually used the Shazam copied link (under the “share” option) that I pasted here: I used Shazam to discover Fantasia On A Theme By Thomas Tallis by Dimitri Mitropoulos & New York Philharmonic Orchestra.
https://www.shazam.com/track/98028398/fantasia-on-a-theme-by-thomas-tallis. I truncated it a few ways and it eventually appeared in the batch of displayed album covers. Not a cinch, but it after a few tries with using the link info, I did finally find it. Took a few minutes, so the searching needs your patience.
Let’s try what you mentioned; Tchaikovsky's violin concerto in D major, op. 35.

48 Albums appeared (some were Beethoven).
Then you can upload an artist and read their profile (truncated in the pic here)

(
Any blue words are links that you can click on (over half of Julia’s link doesn’t appear in the pic).
Then there’s the new albums that appear under the Tidal page/classical, 11 pages like this:

I think you’ll absolutely love Roon, let alone the sound quality.
Roon will also catalog all of your albums too, so you’ll be able to search out info on them as well (you might learn something new about your music that you didn’t know).
If you try it and prefer Qobuz over Tidal, let me know your thoughts about Quobuz.
