Such notifications won't be ignored as isVisible() returns true for iconified windows
Verified the scenario:
 - window displayed (WWindowPeer.initialize() calls updateIconImages())
 - window iconified
 - changed DPI setting (WWindowPeer.updateGC() calls updateIconImages())
 - window de-iconified (with properly updated icon)
