If I get teeth whitening, will all my teeth become uniformly white?

Lately, I check this color every time I look in the mirror. At some point, my teeth turned very yellow, so it keeps bothering me.

So I became interested in teeth whitening, but currently, perhaps because I have a lot of overlapping teeth, even the yellow color isn't uniform; some teeth are yellower while others are less so.

If I get a teeth whitening procedure in this condition, will my teeth become uniformly white? Or will there be slight variations, like my current tooth color? I'm curious.
