Is it possible to extract that info from the equivalence value?
I understand that the higher the equivalence value the better. Category and rank can also be extracte
No, it's not possible to extract that information. The lookup table contains only the equivalence values, which are broken into hand type and rank; no other information is preserved.
If you need to evaluate millions of hands per second and get the winning hand for each, instead of just the rank, you'll need to use a different evaluator. If you only need to extract the winning hand rarely, you could use this evaluator, and resort to a slower method to find the best 5 cards when necessary.
