Mistakes all around imo. I'll try elaborate my own understanding of it.
Chakra may take physical and spiritual energy to mold, but I daresay its not yin and yang releases we're talking about, cause then as aforementioned everyone would be Hagoromo. If anything, its the energies in their raw, unfiltered state, not something you can call a release. Kind of like how we have just plain blue chakra, and then elemental sorts like katon et cetera.
Yang is physical things, be it healing or bodily alterations. Choji changes his size, Kiba turns more beastly, Naruto heals with his hand mark, and so on.
Yin is spiritual, be it either purely the obscure spiritual sort such as genjutsu or those spectral ghost things Tayuyas three beasties had, or then giving something usually immaterial such as a shadow an actual tangible form.
Applying yin and yang to some technique that isn't innately of the release...up to ones own interpretation whether it works or not I guess. As examples, applying yang to katon chakra might produce a physical change related to it, such as lifting body temperature, radiating heat, perhaps emenating flames from tenketsu instead of usual spitting it out from the mouth. Applying yin is a bit more obscure, but figure it'd be either side effects such as affecting the stamina and or spiritual energy directly such as Tayuyas ghost, possibly form changes outside of what typical spacial manipulation can do such as turning an ever so typical stream of fire into a rope instead.
Case by case really. There isn't any uniform, guaranteed result that can be applied to everything in narutoverse.
But what of yin seal release, isn't that yin release? I doubt it, its probably just a fancy name for it without any real meaning, buuuut if you really insist on it then if anything its probably speaking of the seal itself, not creation rebirth. You have been after all amassing chakra to a single point in the body for three years or who knows how long, its common sense that it'd take special means to hold that much power in check.
