I haven't kept up with this thread, but from some previous posts it appears that most believe Queen Margrethe II of Denmark permitted her relatives in the former royal family of Greece to remain Prince(ss) of Denmark even after her own junior-line grandchildren were stripped of that title effective January 1, 2023.
However, has that been established as a fact, or is it merely an assumption at this point? I am not sure that one can rule out the possibility that Queen Margrethe II may have also removed the Danish princely titles from the Greek former royal family without issuing any public announcements. Unlike Prince Joachim's children, the Greek cousins almost never used their Danish titles, and the average Danish citizen may not even have been aware of them.
Is there evidence that members of the Greek ex-royal family have claimed or utilized the title or name "of Denmark" since January 1, 2023?
For what it is worth, the English version of the family's official website does not appear to reference Danish titles. For example, the following is quoted from its FAQ:
Here is the correct form of address: Queen Anne-Marie, former Queen of the Hellenes. All other members of the family are similarly styled.

And the press releases of family weddings and funerals naturally do not use it either:
The funeral service of Prince Michael of Greece was held on Thursday, August 1st, 2024, at the Church of Saint Theodores in the First Cemetery of Athens.
The Greek Orthodox wedding ceremony of HRH Princess Theodora and Mr. Matthew Kumar will take place on Saturday, September 28th 2024 at 5:30 pm at the Metropolitan Cathedral of the Annunciation in Athens.
The Greek Orthodox wedding ceremony of HRH Prince Nikolaos, now known as Nikolaos De Grèce, and Ms. Chrysi Vardinogianni will be held on Friday, February 7th, 2025, at 6:00 pm at the Holy Church of Saint Nicholas Ragavas in Athens in a private ceremony amongst close family and friends.
On Friday, February 7, 2025, at 18:00, the Greek Orthodox wedding of Nikolaos De Grèce and Chrysi Vardinogianni took place at the Holy Church of St. Nicholas Rangavas in Athens.
Danish Billed Bladet seem to exclusively refer to Nikolaos as "Nikolaos de Grece" even though the GRF's website clearly still refer to him as "Prince Nikolaos" so they're definitely confused about the titles.
The most recent press release on the family's website refers to him as Nikolaos De Grèce.
