Samsung Canada published an Oreo update notice, which fills in many more devices than were listed on the Turkish site and there are some differences in the dates (that was expected with staged rollouts).

Here are the phones scheduled for an Android 8.0 Oreo update and the planned release dates. Again, this is from Canada, so some of these have already been updated in other regions.
