I am a bit confused about this, does this include the bloom effect or is it for your own bloom effect to look better? Also could i apply it to objects/my whole screen?

The purpose of the library is to render the effects in a way that doesn't harm the pixels directly (like in the example images), so it is necessary to have the Bloom effect separately in fact, which is not included. This library is not something you apply to objects, but the whole screen (this done automatically). So yes, it is a facilitator, which can be used with Post-Processing FX, for example.
