Different games may choose to disclose some additional information Google and Apple do not require. Some other games may have additional rareness such as Ultra-rare but it doesn't mean Jagex also must add an Ultra-rare to their rareness categories just a few games have that. Note that Google and Apple have no such requirements.
Likewise, Jagex also lists odds of their Clue Scrolls and Boss loot but it certainly doesn't mean all the other games also need to list odds of their Clue Scrolls and Boss loot equivalence neither. This is obviously so because Google and Apple do not require such information.
