The situation when he talks about CGI and when he talks about the show are split with a dialogue with the therapist. These two scenes don't seem related:
- He talks with different people (in the second scene his interlocutors' faces cannot be seen but they have different clothes and hair)
- The following scene (after another dialogue scene) is done in a similar manner - it's the same party, but different situation.
This means that the only information meaningful for your question is given in this single scene when he actually talks about the show. These two sentences are little to go on, but they suggest that he probably talks about one of the recently remade Danish crime/drama shows, i.e.:
Most probably he means the first one as it's more popular and (in my personal opinion based on watching only the original shows) definitely darker in tone.
However it is also possible that he means the movie Brødre aka Brothers remade into Brothers.
Finally, chances are that the writer didn't have any specific movie or show on their mind, but rather was referring to the increase of Scandinavian Noir popularity in the last years (mostly in literature, but also in cinema and TV), which is sometimes referred to as Scandinavian crime wave and resulted in a number of English-language adaptations of Scandinavian crime literature and remakes of their movies and shows.
