No, Gatherer's blind should not get through immunities and resists. It will be fixed, but increased to 2 seconds for rebalancing purposes. Not enough to make anyone reroll Gatherer for PvP, but to keep it from being a flat nerf.
Note that during the course of investigating this report, the most complicated Nodiatis thread in existence needed to be updated with more precise info that differentiates between a) color-based resists and b) immunities and effect-specific resists, particularly when it comes to AoE casts. It also now explains when the "you cannot protect yourself from yourself" clause comes into play, and some other caveats.
