A hybrid with what is my question? Sukhakulii is so dominate in a great many crosses, I don't see any indication of any other species involved if this is a primary hybrid. If you are thinking that it is a bit undersized and the petals are narrow, couldn't that be from culture or from a young seedling? Line bred Suks have better size and form but not everyone is going to be gorgeous,
I would let it flower twice more at a minimum and see if it might improve with age or improved culture. I think it is just too soon. I might have staked it.
