I would guess that the kind of plastic resin that's used for the walls reacts with heat and can easily be permanently marked.

Funnily, the same approach is often used for acoustic / noise issues. Add music / other sources of sound to try and mask the acoustics issue (unsuccessfully).

Reminds me of modern API layers bolted on top of crumbling legacy systems

A common approach. Many of us wear blue and black jeans, few white.
The women who wear white tend to choose fabric that doesn't stain easily, an approach TfL might have considered earlier.

No surprise you're taking the least charitable view possible.
Perhaps what they're doing is cleaning and then looking for a way to mitigate the need for intensive future cleaning. Seems sensible.

Isn't it the basis of active noise cancelling? It's pretty successful.
Yes and no. Active noise cancelling works well at a point and against some common kinds of noise, but if you want to act on a large area such as a tube station, active noise cancelling won't work. Much better to introduce a bit of white noise or music, that makes e.g. the clack-clack-clack of footsteps on the stairs much less noticeable in the wider area.
