Are you sure it's

    camPitch = math.degrees(math.acos(dv3))

and not

    camPitch = 180 - math.degrees(math.acos(dv3))

CamPitch = 90 means the camera is viewing toward the horizon. 0 indicates straight down.

I can see you set the roll to 0. But the roll is given in the csv, row[11]. It is correct as-is.

For the heading,

def calulateEquirectangularHPR(dv1,dv2,dv3):
    dv1 = 0.596300721
    dv2 = -0.802622733
    dv3 = 0.014901141

    rootOfSqrs = math.sqrt(math.pow(dv1,2) + math.pow(dv2,2) + math.pow(dv3,2))
    nv1 = -1 * (dv1/rootOfSqrs)
    nv2 = -1 * (dv2/rootOfSqrs)
    nv3 = -1 * (dv3/rootOfSqrs)

    camHead = math.degrees(math.atan2(-nv1,-nv2))
    
    ...

is correct. But if you want to be more accurate,
use:

(90-row[13]) if (row[13]<90) else (450-row[13])

For the pitch, for accuracy use:

90-row[12]
