Are the adjectives "utopic" and "dystopic" correct English words?
The Oxford English Dictionary has three citations, all from the twentieth century, illustrating utopic, of which the definition is given as ‘That embodies or proposes utopian ideals.’ There is no entry for ‘dystopic’. If you wish to use either word, it would be wise to do so, as always, only if it will achieve what you want it to achieve, taking into account the nature of your likely readers or listeners.
