Have you tested a new scene with just a cube and the sequence applied in a CoronaMtl, just to check all works in that scenario? Also, strange question I know but I will ask :) Are you sure the texture isn't animating in the main scene (though you may need to remove the non-Corona compatible elements in the render set up and the Background object) - I only ask because with camera moves, motion blur, and the relatively slow animation in the sequence, it could be that it is animating, but just isn't totally clear that it is changing. I know it wasn't clear to me just looking at the realtime viewport in C4D, I had to render and do the A/B to be sure something had changed :)
For the Background object, that won't work for sure since Background objects are not supported in Corona for C4D (at this time).
