Yes, if you were to argue it later in court, you would argue that technically it was a judgment to enter the stipulation and dismiss. And the court may strike the "Judgment" wording in the proposed order. But Nintendo presumably wrote it as a "Judgment" knowing the value that such a designation has.

Further, most stipulated settlements don't include substantive findings of fact, and again, Nintendo drafted that section explicitly to blur the line between a court's finding of facts and mere approved stipulated findings of fact. With this order on the books, it will be up to the next case's defendant to later argue that it wasn't equivalent to any other trial findings of fact and order.

Yes, it doesn't technically create precedent as a trial-tested findings of fact by the Court, but a competent litigation attorney would argue that it is probative of the factual issue and fudge the wording in a brief well enough to argue effectively the same.
