Ride FJ this morning and the screens were lit up brilliantly, as Seth said. I'm worried it may be to a fault, though, as I noticed several dark objects appeared washed out as a result. But overall, it's a big improvement. I also noticed another lighting upgrade in the Chamber of Secrets around the basilisk skeleton. I could see the area around there pretty clearly. Didn't notice any light leaking from carousel 3, and the ride profile seemed unchanged, though still excellent. Ride was in fantastic shape from what I saw.
Edit-Last time I rode was in early January.
