Language is strange. Do you think there is a difference between 'God is one' and 'there is one God'? Is there a difference between unity and uniqueness?
Larry Hurtado has a video on early devotion to Jesus here. It is quiet scholarship. But like some others he uses a really strange word - binitarian. What happened to God as Spirit? Trinity is of course an equally strange word.
I do agree with the video that the evidence is very early that the risen Jesus was identified with God and as such is considered 'divine' and was attributed glory unique to the trust that belongs to God only. But is this really an exercise in counting? Or is there a good way to express such mystery?
