Is this what stuck or hot pixels look like?

I've had my A6400 for 3 years. Last week, some strange red/purple/blue marks started appearing my photos. The marks are always in the same place, with all lenses. It seems like the marks appeared for the first time after switching lenses while doing some landscape photography.

I've tried a factory reset, adjusting the time/date (supposed to remap the sensor), cleaning the sensor. 

I've attached an example photo, you can see the marks in the middle of the sky. Is this what is known as stuck or hot pixels? They seem to look very different from other examples I've seen online.

Should also add that the marks are also visible in the camera's LCD screen - not just in the final photos.

Hi Paul, since the spot is appearing on every image and on every lens, I think the issue is probably from the sensor and it needs to be inspected by an engineer, you can contact them from here: https://cutt.ly/AX7sVzc
