If you got them from different batches at different times then yes, it is perfectly likely that they are not the exact configuration. I cant see any difference in the lighting over the tank from the picture so it should be fine. There really is no solution to this issue, cant really change out the leds to match. I mean you could, but its soooo not practical.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
