2013 Prius Head Gasket?

Hello,

Wanted to ask for your help diagnosing potential head gasket on my 2013 Prius at 220K miles.

*Please see attached view in cylinder 1 where I think I see coolant droplets?

symptoms
- slowly losing coolant from reservoir can’t find external leak
- started with misfire (rattle) on cold starts then progressively moved to misfire shudder for 1-3 seconds every stoplight once engine heats up - otherwise drives normal avg 45-50 mgs
- no codes (but did have p301 cyl 1 misfire months ago)
- cyl 1 spark plug looked either lean or maybe a tiny bit washed

tests
- compression (cyl 1 - 120 with other 3 between that up to 130)
- exhaust gas reservoir test (passed)
-ignition coils passes

What I’ve done
- cleaned egr valve, cooler, pipe, and intake manifold
- new spark plugs, air filter, oil change with filter, air filter
- new injectors
