I’m a golf ball nerd and am well informed. Even about the tour only balls. (But I buy the Pro V1x practice balls cause they are the same thing for less money...)
Anyway, I came across a couple dozens of Pro V1 practice containing numerous Pro V1+ balls. The alignment arrows suggest they are 2015 model...
See photo. Let me know. I’d assume it’s a tour only ball that failed to pass final inspection.
Got 2 dozen Pro V1x practice cause I know for sure what they are and how they preform.
