Are you by any chance wearing spectacles for far-sightedness or reading glasses?
I am wearing a strong prescription pair of spectacles for near-sightedness (L -6 diopters / R -5 diopters), and they are high index lenses with a high level of chromatic aberration. With those on for me the red actually seems to step forwards, and the blue is set further back. Very noticeable when I turn my head a bit whilst looking at the screen.
EDIT: when I take those spectacles off, the image seems flat. _________________ Mark

I can stay in front of my computer with them on or off.
Still a tiny bit 3D with them off and more pronounced with them on. _________________ Moderator Himself

The effect can appear much more pronounced when suitable images are viewed while wearing eyeglasses needed to correct myopia, with the effect almost completely disappearing when the glasses are removed. |
That is exactly what I experience! _________________ Mark

According to that, I experience negative chromostereopsis. _________________ Moderator Himself |

I have 0,0 diopters on both eyes, and I don´t see any color protruding above the others. But I see a 3D effect within the structure of the LEDs itself. Thank you for sharing this. I´ve never seen working LED that close. _________________ Cheers, Gerhard |

Never seen them either. It was a surprise for me to see that pattern. I photographed them before but never at that magnification.
I might be the first one to do that ( except the lab people).
I looked for something similar in Alamy, Getty, Shutterstock, Google images, Istock, and all I found was the pattern seen at around 2-3 X magnification. _________________ Moderator Himself |

That's actually the rgb filter layer -- like the colors were squirted from nozzles.
Explanation from some seeing depth reversed from others is illustrated thus:

Notice the blue pattern can appear above or below the red towers -- like the common corner illusion that reverses...
