fix(ios): isDisplayZoomed on iPhone 12/13 mini

[ffraaz]

Description

Fixes #1581.

On iPhone 12 mini and iPhone 13 mini, isDisplayZoomed() always returns true, independent of whether Display & Brightness -> Display Zoom is enabled.

We fix this issue by changing the comparison operator (see here).
