I'm definitely not an expert on these genes. But from a quick research I would say there is definitely no way you can rule out "Candino" yet. I've looked at a ton of pictures online, and at that age, they do resemble yours. It seems like the lavender comes in later?
The "high contrast" albinos I've seen had a far more "stark" contrast between white and yellow.
Your babies contrast seems a bit "softer". Also, esp. in the neck area, there seems a pinkish hue to the white. I've noticed those same things in your "group shot".
To be 100% sure you will probably just have to be patient and give it time..
Do you perhaps have a good "side shot" showing the flames on the side really well? I know those shots are harder to get, esp. by yourself. The hatchlings aren't really impressed with that kind of manhandling, lol...
