According to Porter's site and the conservancy, the APA did not include blue eyes in the SOP. No one really knows why... Hmmm its a puzzle...A Black turkey is Black based and has brown eyes but a Black (BB) based White turkey is also recessive white (cc) and has blue eyes. I do not know whether they found this out through trial breeding or through DNA testing but this has been established for a long time. If you want an in depth explanation of how it works, you should contact Kevin Porter since the information comes from his website.
