It's give and take, my guitars will buzz a bit in about the same positions on the same strings with this kind of setup. (I've gone with higher action lately, so I no longer have this "problem".)
With this amount of relief and 2.0 mm action on the low-E your strings (depending on how smooth the bow is on the neck) can be almost parallel to the fretboard from about fret 12 or 15 to the 24th, so buzz is going to happen to some extent.
Play at your normal volume through your amp, just PLAY, don't play those strings unless it's called for in what your playing and see if it's tolerable, or even noticeable.
Sometimes when we're checking for buzz we'll pick a little harder than what's 'normal' when we play. I've checked guitars like this and realized I was really digging into the strings a lot harder than I usually do, I backed off and just played and found the guitar didn't buzz at all.
Now, if the strings DO buzz too much for your taste when you just "PLAY", a fret level may be in order, or you may have to learn to live with slightly higher action.
If you have a heavy hand, I'd say try the higher action. Less buzz, better tone (subjective) and personally, now that I'm used to it I like having the strings fight me a little. I feel like I'm playing something, something that's pushing back and making me work to play my best.
My technique has actually improved quite a bit since I raised my action, but that's me. :-)
