In DC we had a similar change over. My complaint is just that it is incredibly tacky. It's much brighter than ambient lighting is.
Our metro system is facing a huge budget crunch (the Feds stopping COVID money, and the 2.5 states involved have been very unhelpful at providing funding). I get that advertising is an appealing revenue stream. I just wish we could do it in a way that wasn't so rambunctiously over the top; I wish we could preserve some level of taste.
It would be nicer if they would just end the advertising.

For non locals, this is in a long walkway between access train and terminal, is lit in bright blue moving images, and plays a silly song about interest rates at high volume for the entirety of your time in the tunnel. It has cemented my desire to never do business with PenFed, for sure.
