I have had personal experience with this, if you do LOCA and are not careful about it dripping into the backlight and giving a Pink hint to the screen you can do LOCA. We also remove the backlight before refurbishment and then replace the backlight back again. This is cheaper and better than OCA as well.
Any issues in OCA makes it difficult for a redo but LOCA is easy to remove and clean and redo.
