All vpi are a recessive line bred t+, but there are other t+ lines about normally central American lines which are not compatible with each other to produce a visual t+ any way , they class it as a caramel albino,
Brian's boas on youtube, posted a video think it was Monday this weekn on this very subject, definitely worth a watch and he mentions the line bred pink panther gene on there too.
Hope this helps a bit
I'm getting this cb19 vpi jungle in a few weeks he's pink panther too his pinks are just starting to kick in
