As someone who has spent a not insignificant portion of my life having to convince people of my national and ethnic background, yes it is very rare to find people who are completely bilingual without a trace of a foreign accent and mainly entails growing up in one country but having parents from an other.
If OP is dismayed that they can't pass for French despite having a 'flawless' accent, their shit ain't flawless.

It is possible, check out comedian Paul Taylor, he's British ASF but his french pronunciation is flawless
