The "bright spots" were damage to the light guide that let light out when it shouldn't. I don't know if they were holes or something else. They are a manufacturing defect that was common in early e-ink devices with frontlights. They happened for manufacturers. As far as I can tell, they have virtually disappeared. I can't think of the last time one was reported here and I don't think I checked any of the last few devices for them. But, they were obvious enough on the Glo that had them that I didn't actually need to look for them.
@LivresInOz: Honestly, just use the device. And play with the settings. You will see the problems. If you think something is a problem, then it probably means it is a problem for you. But, if you want an opinion from us, ask and post a clear photo that demonstrates it. And looking at your list of "problems", on the "wedge issue" is one that can think of that applies to the Forma. And I've never heard of Kobo devices "flickering" in a way that anyone could actually see.
