Maybe defining your goals would help.
Sure, winterizing in ethanol will remove some of the stuff you didn’t mean to extract (fats/waxes).
Yes, you can also get some color improvement (in ethanol) using the right absorbents. See Eg: TheLostBiologist Bucket and Post Processing Tek for Golden Extract
…but you’re gonna loose many of the lighter volatiles when recovering/removing the ethanol.
Does that matter? Depends on where you are and what your plans are.
You won’t win any competitions with room temp BHO that has been winterized in ethanol, but 10+ years ago it was absolutely possible to extract at -30C, winterize, and achieve shatter that placed here in Oregon.
In your locale you might still be able to outshine anything else available.
