The App Store Connect API documentation still doesn't list the new 6.9" iPhone display type: https://developer.apple.com/documentation/appstoreconnectapi/screenshotdisplaytype
I already opened a similar topic about the new iPad Pro 13" screenshot type in May (4 months ago), but nobody replied and that screenshot type is still not listed in the specification. I also created a bug report in Feedback Assistant back then, without any reply.
Why does it take so long to update the API specification?
