light bleed will not damage anything. there will be SOME light bleed in all of these tablets. its a part of the manufacturing process. some may see less light bleed than others so YMMV.
one should not wonder what other people are doing, as each persons view of light bleed will vary.
if the light bleed is a bother to you, return it. it is not guaranteed if you will get one with better or worse light bleed, so keep that in mind.
Build versions will also not give one an idea if its better or worse. any mass produced product on an assembly line will have QC issues.
