Some devices have significant drift due to temperature changes, yet we only calibrate at a given temperature. Take the case of an NI-4071 DMM (7.5 digits of precision). If you calibrate at 40 degrees but you use at 50 degrees, you will want to re-calibrate at something closer to that even if the calibration is still valid time-wise.
So yes, I think there's value in displaying it, at least for some devices.
