As of the Epilogue Hotfix Update (2021-04-23), this is a screenshot of the complete progress chart.
See the pages Perks, Spells, and Enemies, for links to more details.
The message "Discovered the secrets above and below - N secret(s) found" is calculated based on the number of five Endings-related secrets you have completed (Greed ending, Toxic ending, Peaceful ending, entering NewGame+, and collecting a corrupted Orb of True Knowledge), plus the number of unique Orbs of True Knowledge you have ever collected, up to 36. There are a maximum of 41 secrets, from unmodded playthroughs.
The 'Enemies' list has a denominator of 171 for 100% progress, but there are 172 enemies in the game, which often leads to the Progress screen reporting 172/171 or 100.6% completion for experienced players. This is a result of the game tracking progress for both left-facing and right-facing Torjuntalaite - their stats are combined in the icon, but each direction will result in an additional enemy killed for Progress.
