The answer
No. Checks can be silent, and reviews can use VAR information without a pitchside viewing. Not visiting the screen does not prove that no check occurred.
Practical example
Distinguish no monitor visit shown on television from no check. The first describes an observation; the second requires further evidence.
What to check
Check the relevant edition of the Laws of the Game and competition regulations. Sporting rules and bet settlement rules answer different questions. The examples above do not describe an actual event.
