The light leak issue is real. Even with a lens attached, but with lens cap on, the issue can be replicated. It should not have happened for a camera of this price. The real problem is not light leaking from the light of your top lcd panel. It is the light leaking in from outside the camera, i.e even if the top lcd light is off, your ambient light will affect the metering. That means, if you do the test in outdoor, you will get different exposure value just by using your hand to shelter the top lcd panel. Some people say canon probably have compensated for it. That IMHO, is rubbish. Some people have the light leak, some don't. So how does canon know which has it or which doesn't? How will canon know which to compensate, which not to?
However, from my limited testing yesterday, it DOES NOT CAUSE ANY REAL PROBLEM. Not even metering issue. Why? This is because the problem is only repeatable with both the lens cap and viewfinder cover on. That probably means it only happens in complete darkness. Anyway, if one is shooting with the lens cap on, the light leakage is probably your last problem.
BUT wouldn't that mean if I was shooting low light, like city scape at night, the problem will affect me? Nope, unless you belong to the 0.1% of canon users who will actually use the primitive 1960s style viewfinder cover for a short 10s exposure. Anyway, for such shots, I will rather trust myself than the metering system. For anything longer and the really really really low light, like 200 seconds bulb mode long exposure, you are using bulb mode...which means you are the metering system...
