Is this “pinched mantle”?

[RGoltz]

I apologize as I’m sure this has been asked before. I have read some threads and the article “Diagnosis and Treatment of Pinched Mantle Disease” by @OrionN but I want some experienced confirmation and recommendations.

I have had this Derasa for ~4 weeks and not long after obtaining the clam noticed this area on the left front quarter where the mantle sort of “cuts in” toward the shell. Please see photos, I apologize for the quality.
