Just as an example,... we had a event wich the movies are BLACK and WHITE, and we achived 5 layers of 1080p... so all depends on the content.
the jpeg algorithms used in most codecs are sensitive to data rate of the movie-

the more information in a frame - the higher the data rate - the longer it takes to decode.

black and white movies usually have lower data rates - so can be decompressed faster

each frame in a movie ( in most movie files ) has different amounts of information - and decompress time varies throughout movie playback-

so its not dependant on the weather - its dependant on the movie data rates - and this varies on the type of images.
and everyones images are different.
