Is this tree grafted????

[Akmal1]

Hi , I planted this mango tree and was told it was from a graft but I am not sure. How can I tell without waiting years for it to fruit?

There appears to be a graft showing in the last picture and it is where a graft is supposed to be but, in pictures 1-3 there also appears to be a graft about 4 inches above the soil. If you were to dig away the soil and expose the root flare you could probably tell if that is a graft or not. In any case the root flare needs to be exposed.
