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

I have a new Macbook Pro 16". I got it in about March.

Intermittently, I have seen the screen suddenly change tinting. I have not been able to replicate it nor figure out a certain timing. Just, out of the blue, it goes from a normal view to a view with a blue tint. I have included a video at https://youtu.be/BSRi4HCGj-Y. You will see it happen at 0:04, 3:25, and 3:44. There are clickable links in the description.

I brought it in to the Genius Bar. He saw it himself. He did a hardware and software check. No issues. He suggested I reinstall the OS. I did that. It's still happening.

MacBook Pro 16″, macOS 10.15

Maybe you have "Truetone" checked in System Preferences > Displays?

Just for comparison, I have a similarly configured 2019 MBP 16" which does not exhibit this problem. It seems to me that a defective sensor could cause the Truetone thing to misbehave. But I could imagine software causes as well. You have some software from Vidyo which may be considered a suspect, but you have quite a number of other third party things running which could be suspect as well. It's tough to rule things out when the problem is intermittent, I know.

Your addition notwithstanding, I was just suggesting you turn it off and see if anything changes.

Standard troubleshooting stuff:

Does this occur for a different user, e.g., Guest? How to test an issue in another user account on your Mac.

Does this occur after starting up in Safe Mode?

Consider the possibility of a third party software conflict. EtreCheck can be used to investigate what is installed. You can post the report here. Someone might spot something.
