Why does my screen sometimes change to a red amber tint to blue bluish tint?

One of the issues I have is that it's so intermittent that it's difficult to trace. For example, since my genius appointment 2 weeks ago, it's only happened for one day, and that was like 2 days ago. So for 2 weeks, it "worked fine".

I think unchecking True Tone is a good tactic, but, given that I can't trace it, I'm unsure how to troubleshoot appropriately. If it doesn't happen for a month, is that enough time? Will it take 2 months? It's hard to trace.

Same thing with the "guest user" or "safe mode" situation. Hard to trace or track because I can't seem to recreate it on cue. It just "happens". I was fortunate to catch it on video and for the Apple Genius person to see it in person. But, of course, that doesn't help you or me. Ugh.

Below is my report.

Thanks for the suggestions.

True tone is checked. But that doesn't register with me as the issue. When I've seen my display change for what I think is True Tone, it's been a smooth transition--never a snap.

Is this expected behavior that it would "snap" into the new shade? That is part of my observation. It's not a smooth transition. For example, when I've observed a device go from "regular" mode to "night shift", the transition from one shade to another is a smooth transition. When I open up the "night shift" settings in the display settings and move the color temperature dial left and right, it smoothly oozes between shades.

Meanwhile, this issue I'm experiencing is a instantaneous SNAP from one shade to another. That doesn't add up to me.
