I received a bit more info, this time regarding World of Colors revamp.
They will be draining the lagoon come January, and rebuilding the platforms. Then reinstalling fountains, adding new fountains and lighting fixtures. They will be adding 400 more lighting fixtures to the Screamin' supports (they added 200 new already this year for Winter Dreams) which will cover every inch of the coaster, and they reprogrammed the lighting for Winter Dreams as a mapping project as opposed to a lighting design. Which is why, if you look at the lighting on Screamin' this year you'll notice their is more detail and flair. In the section where the lights swirl around they are more curved then angular etc.
Once the additional fixtures are adding, Screamin' will essentially act like a big LED screen.
