Question HDMI Bandwidth Issues based on content?

I'm transmitting 4K, 8bit color, 4:4:4 60Hz over HDMI 2.0. Theoretically, it's under the 18Gbps limit so it should be fine. However, I'm occasionally getting black flashes. It only happens very intermittently, and only when the content is very busy. Can HDMI bandwidth issues be caused by the content of the signal? Or is this just a coincidence? Would a complex animated scene transmit more data than a simple static background?
