You did a spreadsheet, right?
Interesting that you're going by ICE miles, not vehicle miles. My changes become:
10,434 unknown EV (prior owner) but high fraction ICE
9,663 3,767EV so 5,896 ICE miles
10,386, 6,192EV so 4,194 ICE miles
My key wear-out indicator is TBN, and my oil is close enough to 1.0 that I'm happy with a 10K change interval. What I'm curious about are fuel in the oil, and wear products like Al, Fe and Mb, which all follow a similar high-low-high pattern. Hybrids have a unique run/stop pattern; does it show up in the oil?
Fuel could just be from sampling a cold engine (I'll sample warm oil next time), but it's also a characteristic of cold starts. My first oil change was a January change, but the next two are August. There's no environmental effect between the last two, but a big flashpoint and %fuel effect. Need more data.
Wear items should all show a declining trend as the engine breaks in. Three ticked up (Al, Fe, Mb), while others continued their decline (Cu, Si). No concerns, just potential trends waiting on an error estimate to become either signal or noise.
So, quit talking and post some oil results!!
