So, in that video that the guy showed Monster Hunter load time, it was apparent that the TV connected to the Series X was debutting better colours than the one connected to the One X. Is that a side-product of the Auto-HDR for BC games? Or just different TV's at different configurations?
Different viewing angles. Both tv's are the same, but in some tv's the color changes quite a bit in different viewing angles.
I wouldn't read too much into it as it might also be a byproduct of the video's color grading.
