[deepracer] about originally included model 'sample_single_cam'

if we log in deepracer private IP, we can see AWS deepracer control console. Also, we can test "sample_single_cam" model because it is originally included. So, is 'Sample_single_cam model' for every type of track? and if we do not change any hyperparameter and reward fucntion when we make a model, is it same with 'sample single cam model'? I am also curious about algorithm type , hyper parameter and reward funcion of sample single cam!

thanks
