Is This Tree Grafted?

Is anyone experienced enough to tell me if this tree looks grafted.  It all looks like native buds to me but the nursery that shiped it insists the grafted branches were trimmed for shipping.  This would be logical but the tree that came is a single stem/trunk with many buds.  I took close-ups of some of the buds with the good camera to try and find someone to tell me if these look grafted or native.  I am new to grafted trees but these look like native buds not trimmed grafted branches.  My yard space is limited so I purchased a 3in1 for the sake of having pollinators without multiple trees.

Hi and welcome to premies.  That's a great question.

Is it a stone fruit like cherry, peach, etc.?  It looks like this might be the bud graft (see picture below).  There is the main stem that has been trimmed off, then this branch is from the bud graft which looks about a year old.  Could you get a close up picture of that area and we can see if it is grafted there?

It is supposed to be a 3in1 Cherry tree.  There should be a primary with 2 additional grafted branches.  I will try and get a close up of the V but if this is the only graft then this is not what I ordered.

It looks like a single graft from the photos.  There would be three 'v's coming off the rootstock if it was a triple.
