Of course, any Steinway artist would be obligated to refuse to perform on a non-Steinway, no matter what their opinion of it. I'm not sure this assertion, even if true (and it's a hypothetical statement), bears on the relative merit of the instruments.
I do know one case where the Steinway owned by the San Antonio Symphony was considered unsuitable by an artist (I recall that it was Vladimir Ashkenazy). The call went out to the Symphony League, and one of the rich ladies of that organization made her Bosendorfer Imperial available. That piano was moved to the symphony hall that day, and the artist not only performed on it, but told the story and publicly thanked the woman during the concert (which was probably all the compensation she needed).
But Ashkenazy was wide-ranging in his loyalties. He also offered to buy the Mason and Hamlin BB owned by Ansel Adams when he played at Adams's house for a private concert a couple of years before Adams died. Adams refused (as he had refused many other such offers). Adams was trained originally as a concert pianist and had many world-class pianist friends.
