I just checked the film and yes, they do show Indian sepoy troops in the final scene. Good for them at least being realistic in that regard.
I do think that Temple of Doom is certainly problematic in terms of racial issues. But let's be honest, that's also far from the only issue TOD has.
Kate Capshaw, for one. Gratuitous violence, for another (which was apparently toned down significantly from what Spielberg originally wanted to do).
