I have two semi hollow guitars. An ES335 by Gibson, and an Epi Sheraton. The Sheraton is basically a dot with a lot more bling. I don't know the construction of the Artcore but the dot has a center block. This facilitates the mounting of the pickups and stop tail piece. If it was a full hollow there would have to be a trapeze style bridge on the bottom of the guitar.
As with any new guitar I find that you need to concentrate on your amp settings. The dot has basically the same pickups as the 57s, which are paf style and should give you a really good all around tone. I have heard them from total jazz to all out raunchy rock. Again guitar and amp settings are critical.
By full hollow body, I always thought that the Artcore had basically the same construction as the dot and 335 with a center block. There must be different Artcore models. I will have to do some research on them.
Since this Dot is new to you I think you should tweak your amp and tone settings and I think you should be able to get to that "tone in your head".
The Blues is alright!
