I would try running the engine for 1,000 miles or perhaps less, then change the oil again and note what the drained oil is like. If it's just oil, that's a great sign, if it's "bitty" or signs of metal in the draining oil, then you might well have bearing damage.
A compression test will only tell you the shape of the valves and piston and piston ring sealing, it wont tell you what sort of shape the bearings are in unfortunately. With a boxer engine there really isn't a way to know how the bearings are until you've stripped the engine down, some might argue you could remove the oil pan and look but it's not so simple on a boxer.
That's great news the noises have died down. Did the engine oil light ever come on ? Since the noises have quietened down, hopefully you avoided bearing damage and it was simply a lack of oil pressure/quantity in the variable timing/camshaft assembly causing the noises. Time will tell but I'd expect within the next 1000 miles to give an indicator if there's more damage.
I think it was the 2012 that are known to consume some oil. I think there was a Technical Service Bulletin about it - Hopefully someone can chime in about it.
I would try monitoring your engine oil consumption, checking every other tank of fuel to get an idea how it is doing.
Edit: You might this thread interesting: 2011+ Excessive Oil Consumption? (ARCHIVED)
The manuals I believe were occassionally known to consume slightly more oil than their auto counterparts - I'm not sure if it was ever found out why
