Barry, I don't see any evidence of noise reduction (tho you never know). Here's what a short clip I just recorded looks like, using that same or similar RX visual setting:

No noise reduction done here. If your clip was done in a professional studio, it would be even quieter than mine, I don't think I even bothered to close the studio door when I recorded this. For what it's worth, I usually use the "multi-color" option in RX, which makes that same clip look like this:

Suddenly, it looks much noisier :-), which partly tells you that much depends on the visualization. I like this view because it makes things (squeeks, noise, etc) stand out better, which is what I want - it helps me see problems. But that's just a choice - all the options are there in RX so you can pick what works for you.
Your reference track sounds very nice, that sure is a lot of reverb, but it works for that example. Can you play those measures of the piece? (I don't recognize the tune - what/who is it?). If so, that would be a great way to experiment and see if you can match the sound.
