Melanoid albinos have only a slight hint of yellow on them, and are not completely yellow. Additionally, you can clearly see iridophores on the gills, which are notably absent in melanoid albinos.
I am still putting my neck out and saying it could be a melanoid albino, Actually i am pretty certain. Another photograph taken with the tank possibly being outdoors or by a window to remove the flash influence may prove surprising
Often, the reflection of light from iridophores looks golden (as can be seen on numerous axolotl photos posted here/axolotl.org/CC/the galleries/etc). I'm not sure what you mean that iridophores reflect blue/green light. I've seen my fair share of axolotls all over the world, raised dozens, traded 'interesting' individuals, and I have never seen iridophores reflect any color other than golden.
Sorry ,I have no understanding of photography ..wish I did. But i agree this little one is albino, tried looking at the link but it would not open.
Golden albinos are (D/x, M/x, a/a). Depending on the genetics of the parents, you can get white, golden, or melanoid albinos.
