“how would I push it” too high... Are you saying try media with a much higher bitrate?

Yes, your media can have quite a high bitrate, depending on encoding. So if you want to test it, test media with ever-increasing bitrate until you hit ceiling. Those lower values should present no issues, especially with HEVC with which you generally have lower bitrate (although depending on number of factors) comparing with same quality AVC encodes.
