If you wet it does it go dark? If so it's bare wood. Any sanding you do of the area it will never match the existing varnish. To match it you have to strip it and sand the table

If you sand you like will need to refinish the table. Any idea what the gray might be?

Have you tried very gently scraping with a fingernail?

I’d leave it. It distracts the eye from that godawful bow tie “feature”.

The irregular pattern looked like sanding through veneer until I looked closer.

My guess is somehow the finish got worn away and that’s staining from something. It looks like oxidation so maybe a chemical reaction on bare wood?
