The point where we started is me showcasing the fact that it is geometrically impossible to see 443km away according to the earths official size and dimensions. I only mentioned perspective, as you claimed that the original photo somehow does not show the lack of 5km tall obstruction in the form of the physical horizon (which it clearly does).
This is a completely separate discussion, but if the picture does not show mountains to appear smaller the farther away they are, please make a coherent argument that suggests otherwise.
The photo clearly does not provide any evidence for “light bending round curvature and bringing objects up from under the physical horizon by the tunes of many kilometres”. That is impossible to conclude from a single picture without any other crucial measurements needed to support such an extraordinary claim.
