The data that X-Ray builds on is an additional proprietary dataset built via manual data annotation.
It would be entirely possible for Netflix to build a similar dataset, and Amazon Prime Video doesn't have any significant advantage here by its association to IMDB (as would be the case if e.g. all production companies would be required to deposit X-Ray data themselves to IMDB to be eligible for major awards).
Given that Prime Video seems to base its user-facing catalog organisation on IMDB, and that that one is probably the most convoluted of all the streaming providers, I'd argue the are even shooting themselves in the foot by being too closely aligned.
