is it really hologram or simply a miniature covered in glass?
Holograms require lasers, don't they? So I would say the latter.
A miniature, but the relief would be exaggerated by the curvature of the glass, so the image looks deeper than it actually is.
I can't be sure, but this appears to be the Hollow-Face optical illusion. It would be achievable with this technology as well
Hollow face illusion produces a face that appears to follow the observer. This just looks like a sculpt under glass.
My guess would be a painting under the rounded glass piece to make the painting move slightly through the curvature of the glass. But I’m just some guy.
