Well, while the internal reference is not directly steering, if it is being locked to the external reference, at least some warming up is needed before it is very stable. Also, depending on the details of the counters, high resolution interpolators may need warmup to perform well and for the autocal to perform meaningfull values. However, usually it's not very long times and often shaddowed by the internal referece anyway. Just to get a rough reading, no. If you want to trust it and trust the noise, let it warm up for half an hour or so.
