I would say albeit totally anecdotally, it can help it get dark.
When I was young and an idiot, I ran cone air filters (K&N style) on my daily driven cars. I found my oil was super black by 3000 miles, even in a relatively newer engine and in old ones, too. As soon as I stopped using them on our cars, I'd find at 3000 miles the oil would be basically bronze colored, and with 5000-6000 mile oil changes even with conventional/syn blend, it would be less brown than my cone filter oil at 3000.
If you look up some oil analysis on here of people who run cone filters, some have readings like 30-50ppm silicon, when a normal reading is about 5-10ppm, so I'm guessing 5-10x-ing your silicon would make your oil darker. Of course conventionally oil gets darker due to engine heat and detergent cleaning stuff, but I personally experienced my oil get way darker way faster with a freer flowing air filter compared to better filtering one, so it's one reason I'd never put on a daily driven car again now.
