Screen has red tint at night (True Tone and Night Shift are Off)

Hi there, I started noticing recently (soon after I upgraded to Sonoma 14.4) that at night both my computer and my external Asus monitor have a red tint to the screen that seems to get darker the later in the night it is (ie. 4pm vs. 9pm vs. 11pm are different). I have checked and True Tone and Night Shift are both off. Additionally, the color profile for my screen is set to Color LCD. For the external monitor, setting it it's own profile or Color LCD does not make a difference.

In the morning though, both screens are back to normal. Additionally, where my laptop is, once it gets dark at night, the ambient lighting around it doesn't change. So I wouldn't think this is a sensor issue, but more of a time-related setting or issue? I'm not sure what to do though, but this is very frustrating. I have the 2020 Macbook Pro Core i7 13". Please help? Thank you!

Well have not heard this before...

I trust you have made changes ie turn ON True Tone / night shift etc. toggling and making changes, in an effort to evoke changes and compare your results along the way, before coming back to your preferred settings.
