Here, I’ll share my personal thoughts here (note: this is my personal LDS perspective, and I respectfully acknowledge that other feel/believe differently):
The Trinity, particularly the doctrine of co-substantation (which is the part that LDS object to) is HIGHLY problematic and results in many other serious fallacies in Nicene Christianity. I see it making it so much harder for people to understand God, to understand His Love, to understand His Glory, to understand the sacrifice on the cross, to understand each other, and to understand themselves. Still, despite all of this this, I see and acknowledge the deep love and devotion Nicene Christians have towards God and the Savior. Despite their hugely flawed understanding of God, they still pray, live, work, honor, and rejoice Christ as His disciples. So no, I don’t believe you guys worship anything less than the true God.
