Compression test is ok (not that bad). I'm not that familiar with leakdown test results (mostly used by Eric O in SMA youtube). My take on leakdown test is that its aptly reserved for testing severe cylinder leakage, whereas the compression test resembles the real work of the engine in split seconds. But still, the engine hasn't been warmed up yet.

Yes. Wet plugs confirms fuel delivery but have you tested for spark? I've read somewhere that the internal resistor of spark plugs could get damaged in excess heat conditions especially in turbo engines. How about a fresh set of plugs? And, are you using Bosch platinums? (shouldn't be)
