From what I can tell, it also isn't lossless: https://github.com/ross39/new_bloom_filter_repo/blob/main/vi... This looks like it is not storing the diff for any pixel that had the mean of its r,g,b values change by less than 10, which…

…(at which point you might as well just store the compressed frame instead of the bloom bitmap). https://github.com/ross39/new_bloom_filter_repo/blob/4798d90...
