Reproduction steps:
1. Open the attached “BugRepro” project
2. In the Build Profile window, enable Development Build option
3. Build the project and run it on an iOS device
4. In the Memory Profiler (Window > Analysis > Memory Profiler), attach it to the iOS device
5. Capture and inspect a memory snapshot
6. In the Unity Objects tab, observe the “Texture2D” Allocated size
Expected result: The allocated size is low, around 25MB
Actual result: The allocated size is 188 MB or more
