Does converting a YouTube video to .FLAC make sense?

Hello,
I convert a lot to MP3, but recently I've been thinking that since I'm converting, I might as well do it at the best quality possible, because anyway, if I need MP3s for memory issues, there are converters from .FLAC to MP3, for example.
However, I have some doubts about the audio quality of YouTube videos in general. It's all well and good to convert to FLAC and all, but for instance:
Does YouTube allow such large audio files? What I mean is, apparently sounds above 16kHz are not taken into account by Google's platform, and from there, I think that maybe, to avoid saturating their servers, especially for economic reasons, during the upload, YouTube might compress the audio, right? So someone who uploads FLAC or WAV to their video would end up with lower quality anyway; is that the case or not?
Second concern, a bit less complex, let's say: a guy makes his video, all that, and for the sound, he uses MP3 240 kb/s. In this case, converting to FLAC is strictly useless, right? The converter can't "invent" waves that have disappeared; well, I don't know how compression works exactly, so maybe it diminishes the waves and there might be a way to retrieve them, I have no idea.
And by the way, is there a way to know the original audio quality of a video?
There you go, sorry for the long message and the multiple questions; I hope I was clear enough. :3

Hello,
I would also say that there's no point in converting to Flac.
Flac is with minimal loss during compression. However, on YouTube, they compress heavily, and therefore the audio track obtained would have already lost some harmonics that you find in Flac files.
So recreating a Flac from a source that has lost quality doesn't make sense to me.
It's better to make your Flacs from a CD/DVD/Blu-ray or a Vinyl.

I totally agree, at best on YouTube you might have mp3 at 320 Kbit/s and even then...
And you really can't recreate frequencies that were removed during compression, so it's pointless...
And even then, the usefulness of the Flac format is questionable; unless you have very good equipment and a very good ear, there's hardly any interest in it.
Yes, that is correct, good answer.
Best regards.
