Odyssey doesn't have a street fork.
Dirt, racing, flatland. They also have a non 41-thermal fork which is similar to their dirt fork.
If I were going to classify a fork as dirt though it would be similar to a racing fork, but slightly stronger, perhaps thinner dropouts. A street fork I would give thicker dropouts and would build like a tank and have the option for 990 mounts.
Odyssey doesn't make a distinction with a street fork, just dirt, race, flat.
Oh, and in my world dirt forks wouldn't come in 14mm as there is no grinding, and often not even pegs in dirt.
Street is all about 14mm (if you are hard on the front axle (beerman)) and serious strength for the 12 foot gap to icepick chunk on granite.
