Dead pixels on day 2 after purchase of HP spectre x360

[vrallnanda]

Using google chrome  browser for day 2 and I create a new tab (2nd one)

Then screen blacks out and I see a patch of dead pixels

Nothing opens up later on and when I do manage to open I see the dead pixels here as shown in the image I took over phone. It is in the exact center of the screen.

i took images with both light and dark backgrounds. It is really bright cyan colour with dark background

After restarting the PC it did disappear but I am now worried since it is just day 2. 

Do I take it back to the purchase store ?As we have a 14 day window to return a defective product in Germany
