why do i see disk IOPs info on a Hyper-V using Windows 2019 but not on Hyper-V using Windows 2016?

why do i see disk IOPs info on a Hyper-V using Windows 2019 but not on Hyper-V using Windows 2016?  if anyone is seeing this same pattern, can i get a confirmation and maybe an answer why that is?  and is there a solution for this so we can get IOPs info on Hyper-V using Windows 2016?

thanks for all your help.
