Does this look like a dead or stuck pixel?

Hello, guys. I have Samsung s34e790c monitor. Had it about 1 1/2 years, I probably use it about 6 hours every other day. I just noticed today right in the center a grey mark. I'm trying to figure if it's a stuck or dead pixel.

Can I get your guy's opinions? Thanks

You can download the image and zoom all the way in. The image is good resolution.

Is it under warranty?
