Where are people getting the idea that there is an uncensored/different patreon version? As far as I could tell from the devlog, there's only one version, and those are the list of things he has changed. Doesn't matter where you get it, it will be the same. In the dev log, Ocean talks about things he changed in the rework as part of the 2304 renders he did, not things he changed for Steam. SO when he made Amber's blouse opaque, it's because it was a cheap way to show her pierced nipples, but she wouldn't do that as a professional. Same sort of thing, Ocean's changed a bunch of things, not to censor, but to make it more cohesive. Amber's change has nothing to do with censoring it for steam, as there already is partial nudity mentioned to make it pegi 16. Nami's lake thing is probably a nervous Ocean censorship, more to do with making it squeaky clean for patreon.
These are my opinions, but nowhere have I seen mention of a separate patreon version from anything Ocean has said.
