I don't think that's known yet. But M3 was ARMv8.6-A and Apple's been keeping up nicely.

If Oryon is ARMv8.0-A then that's quite a disappointment. The LSE instructions are incredibly nice.

Oryon is also 8.6. V9 comes with sve2 sme etc

The Apple M4 is rumored to be ARMv9, even featuring SME on top of SVE2: https://wccftech.com/apple-m4-adopts-armv9-run-complex-workl...

If true, I'd much rather buy an M4 and use Asashi linux (once it supports the M4) than Oryon, but I enjoy low level coding. Being NEON-only doesn't really bring anything new or interesting to the table from that perspective.
