RGB Led with 6 leads

I got this RGB led with 6 leads. The schematics that I found online did not match the LED that I got. So documenting here what I found out. There are 4 LEDs in this package, with 2 leds for blue, may be to brighten the blue colour since it has the least brightness among the three colours at a given voltage.

Here is a datasheet that is close in terms of everything except the leads.
