If you wanna clear it, it's not too late. I regularly hit my kegs with gelatin after tapping and being unhappy with clarity.
Just sprinkle a packet of gelatin into 100-200 mL cold water, let sit 20 min, warm to 180, let sit 5 minutes, (no need to chill), then vent keg, pop lid off, dump in gelatin, seal lid back up (QUICK, cuz it will foam!), purge/vent with CO2 to get rid of any nasty O2 you just may have reintroduced.
In 24 hours in your keggerator, that keg will be crystal clear. (First pour may be hazy as it pulls out the gelatin, but after that you will be crystal).
