Going to be pretty straightforward in saying that filters can ruin weddings. Look in your phone at the photos from a year for two ago at the filters you were using on your photos, some are pretty cringe-worthy. Some photographers use filters as a crutch or use it because they're lazy. Photographers who de-contrast and play with highlights / adding a yellow filter over a photo are a dime a dozen.  The goal should be correct color reproduction and using your skill as a photographer to produce compelling images through composition, knowledge and also being in the right place at the right time.
