pmset standby is missing
From the pmset man page:


  STANDBY ARGUMENTS
  
  standby causes kernel power management to automatically hibernate a
  machine after it has slept for a specified time period. This saves power
  while asleep. This setting defaults to ON for supported hardware. The
  setting standby will be visible in pmset -g if the feature is supported
  on this machine.
  
  standby only works if hibernation is turned on to hibernatemode 3 or 25.
  
  standbydelay specifies the delay, in seconds, before writing the hiberna-
  tion image to disk and powering off memory for Standby."


The bold text is my highlight.  This would indicate that the two Macbook Pros you're using do not support the standby arguments.

For a list of machines that support standby mode, see HT4392.

I hope this is helpful.
