This should be further qualified.

# blkid /dev/sda
/dev/sda: PTUUID="3db012b3" PTTYPE="dos" 
# blkid -p /dev/sda
/dev/sda: PTUUID="3db012b3" PTTYPE="dos" 

and so I think that 'blkid' entry I referred previously to (with that
PTTYPE="dos" in /dev/sda3 row, believed to be erroneously displayed there),
should have the "/dev/sda: ..." line displayed at the top:
# blkid
/dev/sda: PTUUID="3db012b3" PTTYPE="dos"
/dev/sda1: UUID="fb838405-607c-4723-9355-47ccbf1eb273" TYPE="ext4"
PARTUUID="3db012b3-01" 
...

because BLKID(8) says:
"       When  device is specified, tokens from only this device are
        displayed.
        It is possible to specify multiple device  arguments  on  the
        command line.   If none is given, all devices which appear in
        /proc/partitions are shown, if they are recognized."

$ cat /proc/partitions 
major minor  #blocks  name

  11        0    1048575 sr0
   8        0   39070080 sda
