Is my maxima clam bleached a little bit?

[rowenaad]

I had this clam for 2 months. Its about 5cm. It had solid growth over the months with 2 new layers of scutes and they are significantly bigger then the existing one and i assume thats a good thing? Just today i found part of its mantle has a darker color than the rest (top roght corner in pic 1). Its not shadow cuz when it retract the patch stays there, but from a top view the color seems fine

Its under a AI PRIME 16 to a side and a Luminie astra 20 spot on it. Par is around 250 from seneye. I dont think its burnt by the light but idk ‍
