Higher sample rate than 16 bit redbook

Niave question

I have a 16 bit Audio Research Dac 3 and am interested in whether any newer redbook cds are done in higher bit values.  Is it just a few specific “audiophile” discs or 95% still 16 bit.

I have heard that some recordings mentioned as higher bit rates are regarding their recorded bit rate but then are formatted down to 16 bit for the cd mastering.

I also have have res bluray /sacd/ dvd-a player so I am not looking at that issue but rather would my dac play 90% of the cds out there

Thanks
