Is it possible some of this has to do with climate change? Has our atmospheric condition changed enough to be perceptable as a shift in the Suns light?
The way cameras and all light sensors work depends on the sun's light not really changing. Our definition of pure white light actually is based on the mix of different wavelengths we get from the sun. If the sun's light was changing, you'd see any daylit scenes with some new tint.
Edit: That being said, it is objectively true that atmospheric pollutions affect sunlight. It's a big part of why sunsets look like sunsets. The reason we can dismiss the theory that the sun used to be yellow and it's now white is that our whole notion of white light was always defined by the sun. It's the ISO standard for light and lighting^[https://www.nfi.edu/iso/] ^[https://en.wikipedia.org/wiki/Standard_illuminant#Illuminants_B_and_C].
