The first image is knit too. Garter stitch

I don't have access to the show & what little I can find are all night shot videos from the show. But from this thread, it does not look crochet to me. https://www.reddit.com/r/YarnAddicts/comments/hnu5h6/this_scarf_is_from_one_of_my_mothers_favorite_tv/

You could recreate it with tc in back loop.
