How do I understand if this espressif chip is original or not?

First:

Second:

I am confused because they look so similar, and in different sites and videos I have found with company names or not. Or are all of them original?

Probably, yeah. I don't think anyone is presently copy-catting ESP32's. It's a native Chinese product, which likely makes it unattractive for (Chinese) copycats to try and clone it. Just not enough money in it.

You can't go by the images you see on a webpage. Often, they don't represent the product in every detail and sometimes use a generic image for the ESP module.

If you want to know for sure, then buy a genuine Espressif device kit

But even here on different images we have or do not have company name…

Is it a genuine Espressif devict kit?

I don't know of any way to tell unless the crooks are real amateurs. The best clones are 100% identical, I have lot's, many bought from Ali and have yet to encounter a problem. Buy from several different sources, and if one gives you grief try one of the others. Odds are it's your code, not the board.

The chip (esp32) in genuine in both, it's a question if the board is built by Espressif or by somebody else. As far as I know Espressif always mark their logo on their boards.

In this case, there is both the "module" (the little board with the can on it) and the larger board as well. Espressif makes and sells a bunch of different modules, but some vendors build their boards from bare chips, or make their own modules.

I have the exact board shown in the "second" picture in the OP going by the can markings. Considering my source I can almost guarantee that it is not made by Espressif - the MCU however seems to be genuine.

I soldered two zero Ohm resistors to the RGB and IN-OUT pads (to enable the Neo-Pixel and make 5V output available) and it works fine. I mainly wanted to experiment with the IDE 2 debugger (which, incidentally, still leaves a lot the be desired).
