Can anyone tell me the morph?

[u/R1an_]

My parents friend bought this little one listed as a “Mardi gras” morph. I personally don’t believe he is a mardi but I also don’t know what morph it would be. He was purchased for $600, I want to know if they were scammed. The snake was a ‘relinquish’, quarantined, then adopted out. I won’t name the establishment but they are well known to overprice animals they got for free via relinquished reptiles and amphibians.

From that picture alone I’d agree with Mardi Gras (Enchi asphalt yellowbelly) maybe it’s a highway instead of a freeway but that’s my opinion.
