im pretty sure it'd count towards cure potency cap, not sure though, since this is only how i see it. XD
Healing feather straight up gives cure potency (well enhances healing magic, but cure potency nonetheless)
Korin obi just makes lightsday/weather enhancements 100% work, and i only saw those as X% (depending on day/weather) bonus, not as cure potency, so it's a different enhancement overall.
At least this is how i see it, considering as you couldn't find information i thought i'd give my thoughts about it and how i think it works ^^
P.S.: I hope i made sense, i usually suck at explaining
