"Normal" mode often operates in 8-bit per channel (16.7 million colors). "Extra quality" moves to 10-bit or 12-bit (1.07 billion colors). When you trigger a high-quality refresh, you are asking the GPU to switch from RGB 8:8:8 to RGB 10:10:10 color encoding. This requires significant VRAM and PCIe bandwidth.
