This could have been a short event. Once Uther was dead, Arthur would have lifted the ban of magic.

Or....

Arthur being a sorcerer probably would have strained the relationship with Uther. He wasn't anything like Morgana but constantly hiding and watching others like him being sentenced to death would have stretched it all to the limit. Moreover, as prince he would have been forced to persecute and arrest them.

I doubt that Arthur would have hated Uther as much as Morgana did (his reaction in "The Sins of the Father" was quite ridiculous and exaggerated) but he would have had no other choice than turning against him one way or another. I wonder if he would have learnt of the circumstances of his birth much sooner.

In any case, Merlin wouldn't have had any reason to hide his powers from Arthur.
