The difference between the LG UltraFine 32UN880-B and the LG 32UN88OP-B does not appear to be fully documented. However, there is no evidence of significant technical differences between these models. It could be a mix-up or a typo, as the LG 32UN88OP-B is not mentioned in the available information. If you're looking for a comparison, I recommend checking the technical specifications directly at LG Electronics or comparing the models you have in mind.
