Is the angular diameter distance turnaround real?

Made a video about the surprising feature of LCDM that is the angular diameter distance turnaround:

It seems our attempts to verify this with evidence fail pretty badly.

Are there more current, larger datasets available that you know of?

No turnaround is observed, ΛCDM is a farce. See Fig. 5 in N. Lovyagin, A. Raikov, V. Yershov, and Y. Lovyagin, “Cosmological Model Tests with JWST,” Galaxies, vol. 10, no. 6, Art. no. 6, Dec. 2022, doi: 10.3390/galaxies10060108.
