I couldn’t find an answer and I know I’m not the only one having this question.
What does downloading “high-res aerial photos” actually do? I can’t tell the difference. Switzerland has its textures in higher resolution and I thought it’ll be the case with the US after this in-app download but as I said, I don’t see any difference and the textures in San Francisco or Denver for example look rather bad.
(It reads “Installed” under both regions”)
