Winter Imp from Legendary Task? Summer Imp, where art thou

As the title says - Got Winter Imp, expected it would have been a Summer Imp
Perhaps LT rewards are different from chest rewards pool of available cards (As they are for Mythics?)

Can someone please clarrify?

All imps are available in legendary tasks.


Thanks, I thought that might be the case as per Mythics
(Iā€™m still chasing Summer obviously)
