"8k HD" was a prompt engineering trick from the VQGAN + CLIP and Stable Diffusion 1.X era, since they did indeed have an impact in getting photorealism as CLIP's text encoder is funny like that. When Stable Diffusion 2.X was released with a new text encoder, it broke all these tricks and people were upset. Here's a fun demo of the impact of prompt engineering tricks back in the VQGAN + CLIP days: https://imgur.com/a/SnSIQRu https://imgur.com/a/SnSIQRu Odd to see the same trick work on a completely new text encoder though.
