R/D less than a year old; a pro tech, on the spot to vacuum and recharge, Wow. You're good to go! (although I would have liked a longer vacuum time and a check for leak down of the vacuum). You're certainly in at least as good a spot as when you drove in, probably better.

I would not automatically replace the R/D in this case at all.

You couldn't have made this up if you tried! Great outcome.
