Definitely better than it was 10 years ago. I've visited London once every 1-6 months for the past 10-15 years, and have noted a change. It's still not amazing, though - honestly, if they were to aggressively disincentivize diesel in small cars, I feel like everything would be fine. Subjectively, a day in London seems akin to spending a few hours with a 50cm3 2-stroke chainsaw, or an hour on an old diesel excavator. I do not feel the same way about most US cities, nor even most cities in mainland Europe.
