Yes. Blur kind of gradually spreads color of every pixel into all directions, reverb’s doing the same with sound. Did you know that the simplest type of reverb is delay with super short time? I would personally consider lossiness (or cutoff effect) of blur a side effect of pixel giving away a bit of it’s color to its surroundings. Filter on the other hand is a cutoff that just takes but doesn’t put it back somewhere else.
How tho, it simulates echo and physical space doesnt it?
