Is this a new product delivered?

I am disappointed and doubtful about this phone. He arrived without the official seal LG but with two white stickers. This makes me think of a given screen in the sales circuit after repackaging rather than a new product. The color of the screen is not calibrated the same as LG G3 go 16 I already own. The screen is in the yellow tone. It works fine but I wonder about the products sold by Amazon.
