No, I'll demonstrate an exact allegory of your argument.
The umpiring error shown below (according to your logic) proves that the entire WI series of dominance was orchestrated by home board umpires conspiring to raise the WI to greatness at the expense of their own teams (no logic or motive for this need by provided, in accordance with your own example). So yes, WI may have SEEMED to be one of the atg teams & dominate for 15 years, but really it was all up to the umpires.
Now, go show me the share of wrong calls vs the WI. Start with India tour of WI 82/83 please.
Craig McDermott clearly missing the ball & clipping the helmet- a single error which proves a vast conspiracy which negates the entire WI golden era- seen below.
