Gloom damage questions

Hello, I have a question about gloom damage and resistance to gloom that I haven't been able to find online yet. Spoiler warning: I will need to discuss specific areas, armor, and bosses in the depths. I've explored most of the game and finished all the main quests so don't worry about spoilers in the comments.

Ok so my question is about how normal armor affects gloom damage. I know that the gloom-resistant armor gives you temporary gloom hearts that get damaged before normal hearts. However, does the normal armor you wear affect gloom-infested enemy's attacks? So for example, say I'm fighting a gloom lynel in the colosseum or a frox. When they attack all of their attacks do gloom damage. Does my normal armor affect how much damage they do? Does upgrading my normal armor affect these fights at all or would a level 3 fierce deity set and a level 2 fierce deity set take the same damage from a lynel hit? It feels obvious but I haven't been able to actually test it out so figured I would just ask. If the normal armor does reduce the amount of hearts you take from gloom enemies, what good is the gloom-resistant armor? I only have one piece but does it just protect against gloom on the ground?
