Steps to reproduce:
1. Compile and run in simulator for any device (Edge 530, say)
2. Download a two-colour image (like a QR code, for example) using makeImageRequest() and display, verifying image is valid
3. Store the image in storage using Storage.setValue
4. Recompile for a different device (Fenix 7x, say)
5. Display the previously stored image
Expected results:
The stored image should display correctly
Actual results:
Colours are rewritten incorrectly, with black appearing as pale blue (for example).
