[Feature Request] Remove darkening filter on album artwork from "Fullscreen" player

[Neptune-mk2]

Issue - In my use cases I have found the dark filter that's added in the "fullscreen" mode too dark and on albums/songs with artwork that's already dark its barely visible.

Solution - Do not darken background artwork or make optional in settings

Alternative - Reduce how dark it is and apply only in dark theme, and in light theme (or system if light theme is active) make it brighten instead.
