I think it's best to assume that not every market is the same, what works in Spain doesn't mean it will work elsewhere, and vice-versa. Making a judgment is difficult, because socioeconomics come into play and differing practices of how entertainment is distributed.
UK: Disney Jr had strong ratings, but Disney Channel was weak, streaming is strong but competitive in this market, make a deal with Sky for Disney+ to help boost subscriptions to compete against the offerings on Netflix and Now TV (owned by Sky, but also cannibalises their premium product), and relaunch Disney Jr.
Spain: Disney Channel was popular but expensive to run on DTT and had tough competition against Boing and Clan, plus the DTT capacity was leased, Disney Jr seems to be doing okay on pay-TV, but this can be expanded to include more to become Disney Channel.
