Maybe it's been edited since you supplied the wikipedia link, but it doesn't support your narrative.
One page down, it describes Ukrainian Soviet officials claiming there was no danger from the accident to regional Ukrainian SSR officials. It says that Pripyat was only evacuated 24 hours after the disaster, after more than 50 residents were hospitalized for radiation poisoning.
Even then, the letter to the residents was that the evacuation was temporary, and primarily as a precautionary measure.
The only thing you effectively refute is the timeline, Pripyat was evacuated 24, not 36 hours later, as the parent poster erroneously stated.
The wikipedia article doesn't mention internal Soviet press releases, so you haven't refuted that Ukrainian or Russian officials denied a disaster. However, the parent poster nor the OP haven't demonstrated that officials lied to the public either.
