Visual effects on the character sprite disappear when a transformation occurs such as death knighting and shine knighting. I haven't tested this with chaos reflex but I think it does apply.
Steps to reproduce:
1: Equip hexer with death knighting
2: have the barrier tattoo trait
3: in battle, cast death knighting
4: observe the removal of certain effects
Note: elemental enchantments seem to not be affected
pictured: phantom cloak, brighten, arcane tattoo (barrier), arcane tattoo (warding) (Sorry for bad quality I was trying to upload a gif)
shine knighting result
different test with death knighting and kraken (all the same buffs otherwise)
This may seem minor but visual indication is important info in certain cases, especially if mask of metal or Mysterious is at play.
Edit: Oh god what's going on with the pictures, it worked in edit mode!
Edit 2: Okay, fixed the pictures
