I can't see anything much but the photo is a bit, I think you'd have to see it in person.
Yes, I do think if it's bugging YOU you should contact Dccodes ,why not? The worst they are going to say is "We can't do anything" but if you have concerns you should at least note them. Dicodes is well renown for its customer service so while other people might be inclined to let it go or whatever, what YOU do is completely up to you. So if it is a problem for you contact Dicodes, I mean what do you have to lose? Maybe it's a genuine defect.
I will say he most perfect mod maker is not perfect. Someone was saying the last letter/symbol in TC did not quite fit the screen on a dani or dani 21700, I forget. But it turned out to be just the only way to make it work and normal.
No such thing as perfection eh? But if it seems not normal, then you should ask.
