Good question, From my experience, two things may happen.
1. The higher order will have lower amplitude but only to the extra channels of that order, that means that the spatial resolution of the reverb elemebt will be lower only, as the energy of the signal is given from the 1st channel as far as I know. 2. Higher order material might have higher or lower level on the channels that lower order reverb is added due to phase differences that are natural from the reverb effect. This might affect the final output’s balance between the first group of channels that carry both higher and lower order channels ad the second group of channels that only carry the higher order channels. Again, if I understand correctly, anything added above the 1st channel Will affect spatial resolution and not signal level, please correct me if I’m wrong. On a more przcrical level, if it’s a movie or an audio drama I wouldn’t worry about it. If it’s more technical or scientific I would measure with test signals. Some basic phase cancellation A/B test would give you enough results to decide what is best for your case. Cheers!
