[iOS] NPOT textures without compression uses more memory than a regular texture

iOS

-

To reproduce:
1. Open users attached project "test.zip"
2. Open "SampleScene.unity" scene
3. Select the Main Camera game object from the hierarchy
4. Make sure that "pow2" is added to the Image Reference Texture field
5. Build for iOS
6. Deploy the Xcode project to an iOS device
7. Select "Show the Debug navigator" tab on the top-left and select "Memory"
8. Observe memory consumption
9. In the Editor, select the Main Camera and replace "pow2" with "nearly pow2"
10. Make sure that Non Power of 2 is set to None
10. Repeat steps 5 - 8

Expected result: memory consumption is similar
Actual result: NPOT texture without compression uses more memory than a regular texture
