I've trawled through all known PS2 BIOS's and found a total of 784 mentioned serials, approximately 567 of which are PS1 and the remainder PS2. A few of the serials are not dumped and have unknown titles.

Some interesting finds by searching through the Sony Bravia TV BIOS (PAL and NTSC-J have the same set of serials)
Overall there are 241 serials mentioned, and most of them are PS2 serials (maybe the bravia edition had comaptibility issues..?)
Two undumped and un-wiki'd serials: SLPM-60222 and SLPM-60223 (Exciting Pro Wres 5 Taikenban: https://muuseo.com/veru/items/178
One undumped serial that is listed on pcsx2 wiki as possibly cancelled: SLPS-20390 https://wiki.pcsx2.net/Hissatsu_Pachinko_Station_V9

Way fewer (23 vs 198) serials listed in the PAL SCPH-9000x BIOS, at least that I could find.
