If this pepper was
discovered in a glasshouse 2 yrs ago, it is unlikely that it is a hybrid, as 2 years would not be enough time to create 2 true-breeding parental lines that were striped.
This assumes that, like in tomatoes, the striping is recessive. If the striping is dominant, Enjoya (the stripey pepper) could be a hybrid.
My bet is that it is PVPd and/or they have tried to patent it.
