We simply don't need the intermediate ratio assets while working with React Native, 2x and 3x works very well for hdpi>= requirements. Technically speaking, when you bundle the RN project in Android or when it gets bundled while building, you will be able to see autogenerated transformed image assets in android/app/src/res/drawable which are required for the app to render on target screen resolutions. I would recommend observing those auto-generated assets after building the bundle, you will have fruitful insights about the asset distribution and usage.
