I take it you haven't bought it as 'wild'? 99,99% of the dwarf gouramis are farmed. It would be much more expensive as farmed ones. Often they don't even bother to sell the females, they make fish paste out of those. They do crossbreed the lalia, chuna and labiosa to get better colors. Fish farms in Asia are not particularly accurate with the names of fish, and they do try to pass off weird variations/hybrid/painted fish off as certain species, so the link in India says nothing really... they don't even claim a scientific name.
On Fishbase they have a bunch of pictures of wild caught dwarf gourami's, but they still all have the typical dwarf gourami body shape.
Your fish has not just the body shape but also the anal fin shape of a labiosa...
Mixing in more expensive wild fish is not something that is done in the trade, other farmed variations however...
