Skeletal mesh vertex colors swizzled on Mali devices

We are currently experiencing an issue where skeletal mesh vertex colors are different on certain mobile devices.

What we see is the following:

• Red and Blue channels are swapped.

• It occurs consistently on European Galaxy S7 devices (Arm Mali-T880) but not on the US variant (Snapdragon 820).

• The problem is exclusive to Skeletal Meshes. Static meshes work as expected.
