From what I've heard and what I understand, the screenshots and video we've seen of ToMI so far are from an unfinished product and should be taken just as that. They have said the current graphics may not be final (but don't expect anything drastically different, just lighting, maybe some special shaders?) And given Telltale's turn around time of a game season every quarter, a month's worth of work on a Telltale game is a lot of work.
