As for your last starment. Lets say the display device is the same 27" imace. You take a photo of a mite at 2x magnification with the same lens and...well, okay, equivalent apertures between a ff and an apsc. Display both on the 27" imac, uncropped. Nope. Still not the same image.

It is obvious that it is not the same image because the content captured on the sensor differs.
Also, the final magnification level is higher for the pursued subject captured with the APS-C sensor on the same 27 "screen.

You can also shoot the same subject with an MF camera, with the same optical system that offers a 2:1 magnification and it is obvious that the content of the image will not be the same.

Who says that what captures a 24x36mm sensor is a reference? Why not reference a sensor with a size of 30x47mm, or one with a size of 20x32mm, or any other size?

The projection of an object (or part of it) will have exactly the same size on any sensor, of any size, in the case of the same magnification ratio. Absolutely nothing in this regard is tied to the FF format.

..............................................

For example, a spherical object with a diameter of 1mm, in the case of a magnification ratio of 1:1 will be represented on any sensor, of any size, by a circle with a diameter of 1mm.

The difference in image content between sensors of different sizes is what is reproduced around the pursued subject (for same magnification). If the spherical object (1mm diameter) is photographed on a black background, we will have more or less useless black background around the spherical object.

If we photograph the respective spherical object with a small sensor for phones, with a high pixel density, with quality processing algorithms and an optical system suitable for the 1:1 magnification ratio, the spherical object taken for example will be able to be observed with many details on it (assuming that there are those details), on a decent size black background, unlike what is captured on the 24x36mm FF sensor, respectively a tiny 1mm object surrounded by an unnecessarily very large black surface.

Dude. You arent teaching anyone anything here. You are literally ranting about the most basic principles of this genre, and honestly, I have no idea why
