There's a film on ITV1 at 2305 so I can't see why it couldn't have been shown then, with build-up before on ITV4.

Sounds like a smokescreen to me, either by Khan or ITV who just didn't want it. The got good numbers for the Hennessy cards on ITV4 and incredible ratings for the darts and dumped both, remember, for cheapo Minder repeats.
