Was about to report this and a related issue. It seems that once you get protection up to 20 for any kind of damage it is 100% prevented. So when wearing full netherite armour as follows:
Helm: Fire Protection IV
Chest: Protection IV
Legs: Protection IV
Boots: Protection IV + Feather Falling IV
I think my resists should be 12 (Protection) + 8 (Fire) + 12 (Fall) + 4 (Blast)
However, I take no fall damage and no fire damage.
