Under Cabinet led strip lights appear to be different colors/temperatures

Question

I have been in my home for about a year. My wife just noticed that the led strip lights under our cabinets in the kitchen are all the same except in one location, where they are less "white" and more "yellow". I don't recall the colors being this different in the past. Is it possible  for them to fade or change?
We don't have any remote or programming, they plug into a brick in an outlet under the sink and it looks like there is wiring connecting multiple strips in different locations.
Is this something I can somehow change, can these change on their own? Or is it likely somehow a strip preset to a different color temperature got mixed in?
Side note - not sure if it is related, we had flickering lights in a few places (not the one place where it looks more yellow) - is it possible for some type of damage?
It's a bit hard to capture the light in photos, but here is the diff between two area taken from the same position in the room

It varies dramatically by dimming/color-control method
If we're dealing with multiple modules listening to the same remote, that is a very different picture than common PWM control. If I'm sounding like Geordi LaForge on Star Trek, then you see the problem. There's a lot of tech here.
And I gather from your question that you don't really have the vernacular to get down-and-dirty on the gory details of this system's design.  That, however, is where the problem lies.
If you're dealing with RGBWW or simply WW (adjustable color temp)

in WW's case, that means 2 separate strings, one Warm White and one Cool White.
in RGBWW's case, it has that, plus, Red, Green and Blue.

Typically each of these 2-5 strings is dimmed individually, resulting in a blend of colors. Blending cool white and warm white gives you any color temperature you want, and of course R, G and B let you get funky!
If that's the setup, it's possible that one of the strings has gone out, leaving the remaining string stuck at full-cold or full-warm.  The "flickering" would be consistent with that.
If so, that's likely a simple wire repair.
