Quick google search I found this
Colorado is a diminished value state
Colorado is a diminished value state, meaning drivers are allowed to recover diminished value from the at-fault party’s insurance company. When your vehicle experiences an accident, even if it is fully repaired to its pre-loss condition, the resale value decreases.
Unfortunately you had a hit and run so I'm not sure how they handle that. It might be similar to being at fault. I believe your insurance company does not have to pay these diminished value claims if you are at fault.
As for total loss, it looks like CO is 100%. Meaning the value of the repair has to be 100 or greater than the value of the car. So I doubt they will total your vehicle.
