Possibly need to arrange for mount_nfs to see -o nfsv4
(I use mount_nfs -o nfsv4,minorversion=1)

Then nfsstat shows eg:

terp:/library on /mnt/terp/library
nfsv4,minorversion=1,tcp,resvport,hard,cto,sec=sys,acdirmin=3,acdirmax=60,acregmin=5,acregmax=60,nametimeo=60,negnametimeo=60,rsize=65536,wsize=65536,readdirsize=65536,readahead=1,wcommitsize=2798255,timeout=120,retrans=2147483647
