Would a Russian victory have changed the war?

If Rozhestvensky had somehow won at Tsushima, what would have happened?

Japan would probably have reorganized and attacked again; Port Arthur had already fallen, so victory would not remove Russia's strategic isolation.

One brief answer is that Japan would reorganize and renew the attack. A Russian passage or tactical victory would preserve more ships, but it would not restore Port Arthur as the expedition's original destination. A force reaching Vladivostok would still confront Japan's nearby bases and rested units. The question tests whether a dramatic battlefield reversal could overcome an already unfavorable campaign structure.
