She is definitely using her good shape and pretty looks to attract an audience to her channel. She's not the first one to do it nor is she the last. I recall another American channel doing something similar where the thumbnail shows the wife in certain eye catching situations and clothing. The content may be worthwhile, maybe but they are going to have to do something other than show off their body to keep my attention for more than a video or two. There is eye candy all over the internet if that is what I'm hunting for. I don't need their channel to get it.
