Just noticed a weird white level carry-over bug in my X95. If you start by using the THX (which uses the Super White mode), then select one of the unmodified User modes (using the Standard white level), the Super White mode's attributes briefly carry over. I determined this using the Spears & Munsil 2nd Edition disc's contrast pattern.
Along with the discovery, I've learned that contrary to what some reviewers and posters have said, it seems the projector is most accurate on the contrast front when the Super White HDMI mode is engaged.
Using the S&M 2nd Edition contrast pattern, you will be able to clearly see the projector clips the contrast bars in the Standard HDMI mode. It pretty much looks like this:
However, with Super White HDMI mode engaged, the bars display properly as seen below:
