I am no expert, certainly not on industrial scale bulk order side of things,
but even looking at New Egg single-unit retail, the difference in BDXL (4k capable) vs. lower spec BD is $20.
That is the cieling, for single-unit retail, and should reflect relative price premium, above actual production costs.
So realistically, actual production cost difference in bulk should be like $5, or certainly less than $10.
