Has anyone ever bought a retail film which came on a duplicated Blu Ray disc?

Not a BD, but "burn on demand" DVDs are not uncommon. Even Amazon sells them for series like Night Court.

Any company selling them should notify you that they aren't "regular" pressed disks, because some BD players do not work with recordable media.

Since this is the MakeMKV forum, users here would only care how well they rip, since you don't have to use the physical media beyond that.

I've had BD-R discs from Sony and Film Detective.
