Yes, if your tinted sprites have exactly the same tint they will batch together, but if they are only a tiny bit off they will not batch. So a color of (0.5, 0.5, 0.5, 1) and (0.51, 0.5, 0.5, 1) will NOT batch. They have to be identical. Remember that each unique tint will get its own batch, if you have 10 different tints you will get 10 batches. If you have 100 you will get 100 batches.
You can read some more about draw calls and batching in the post draw calls and defold.
