Compared to https://ocw.mit.edu/courses/mathematics/18-05-introduction-to-probability-and-statistics-spring-2014/readings/MIT18_05S14_Reading24.pdf you have reversed the deltas for upper and lower bound confidence intervals. One of you is probably wrong, but I'm new to bootstrapping, so it might be me who is wrong.

Also, instead of nvals = np.round((n_samples-1)avals), nvals = np.round(n_samplesavals)-1 should be better (gets integer without rounding for default alphas and n_samples)

My bad, didn't notice you use percentile bootstrap instead of empirical bootstrap.
