GetPixel with RGBA32 not working on IOS!

I’ve set my texture to RGBA 32 bit using override for iPhone Option.

Read/Write is Enabled.
Texture is 512x1024 (tried it at 1024x1024 aswell)
Generate Mip Maps OFF
Generate Normal Map is OFF
Filter Mode Bilinear
Wrap Mode Clamp

When ever i do a GetPixel call i get the following error:

Unsupported image format - the texture needs to be either ARGB32, RGB24 or Alpha8

I can only set RGBA 32 Bit with iphone version of Unity Not ARGB32… It works with RGB24 Alpha 8. But i Need RGBA 32bit.

Any ideas?

I just recently ran into the same issue - did you ever figure this out?
