I'm pretty sure it's not, but it may be for similar reasons. Without the modifier gene, tomatoes with the Beta(B) gene are only 60% carotene, the remainder being mostly lycopene. The final 'blush' is the lycopene showing through.
I'm guessing your white genetics is a form of r (note that Beta does not work with r, only R.), but that "qualitative" or "bi-color' genes are causing a late addition of lycopene to the development of your tomato, but it's all conjecture on my part.
