Loss of oil will result in a catastrophic failure of your engine and the only place where oil temp / pressure / quantity is displayed is on this screen.
Not true unless you are using a very subjective definition for catastrophic.
Loss of oil alone will result in low oil pressure, high oil temperature and gradual wear of the bearings over a single flight. As the hours progress high vibration will be rfelt associated with the loss of centerline of the rotors. This often leads to engine stall symptoms due to blade tip and seal wear.
It's pretty easy to see this coming in a timely fashion and to idle the engine or shut it down as circumstances permit.
The data fields confirm the above (see FAA CAAM report) and the most serious events were associated over multiple flights where continued events of loss of oil leaking internally caused an internal engine fire.
There is no need to beome paranoid about things that are already covered in your SOPs
