Anyone with experience with these types of panels know whether the proposed seamless edges are actually possible? I'm a bit skeptical that manufacturing tolerances are tight enough to create a seamless edge from independent panels but I don't know enough to call bs.

In LCD or OLED displays, most of the display area emits light. There are black lines between the pixels, but they are thin, so it's hard to hide a seam in one. In contrast, the micro LEDs on this display are very small relative to the distance between them, "micrometer scale" vs. almost a millimeter. Most of the display area is actually a blank black surface, where a seam can be hidden.

Making smaller displays this way will be a challenge as the pixels will have to get closer together.

Here is their demonstration with sliding panels together:

You can see a little line on certain images (for example at 0:20) but maybe it's caused by the sliding mechanism, because there is no line on the left side assuming they are put together from two square panels same as the sliding one.

Sony displayed something similar at CES a couple of years ago. Didn't notice it until I stood very close. https://pro.sony/en_MK/products/led-video-walls

Yes they are. I have worked with one of these and it looks incredible in person. The edges are seamless (but incredibly fragile).
