Sure - the framing of both SMB2/SMB3 is designated as an "SMB2" packet in wireshark (and in the Microsoft protocol documents) - to ensure it's negotiated SMB3 you need to look inside the DialectRevision field inside the SMB2 NEGOTIATE Response packet in wireshark.

0x0202 SMB 2.002 dialect revision number.
0x0210 SMB 2.1 dialect revision number.
0x0300 SMB 3.0 dialect revision number.
0x0302 SMB 3.02 dialect revision number.

(there's also the 0x02FF wildcard value
but that then expects the client to
re-negotiate a specific SMB2 varient
with another negprot fillowing).
