Forum:SH:Episode Guides and Legends

Some Episode Guides for The Clone Wars seem to recognize some Legends facts about canon subjects. For example, the Episode Guide for "Missing in Action" describes Malachor as a hellish wasteland world and provides an image of it from Timeline 9: The Mandalorian Wars with the lines removed from the picture, making it seem like it was done specifically for the guide. Another example would be the guide for "Destiny" provided an image of the terentatek that is seemingly an animation model from SWTOR. Can details like these be considered canon?
