Your Peace Lily (Spathiphyllum wallisii)
looks fine to me. I've never had one with an upward growth habit and I'm thinking the leaves on your plant were originally in that position because of the way nurseries wrap plants to pack them tightly and truck them to the garden centers. I've been at garden centers of big box stores many times and watched them unload hundreds of plants, packed tightly in brown craft paper with the leaves in the upward position. Once they are unwrapped and have time to acclimate to the surrounding light and temperature, the leaves drop to their normal habit.
You did good by cutting the foil away from the bottom of the pot, otherwise it would be holding water and likely rotting the roots. Peace Lilies like water but they also need good air circulation and oxygen around their roots. I have three that I've had for years, the one in my photo below has actually been sitting down in the water of a fountain for the past 3 years; the roots have grown out the bottom of the pot into the water but the plant is quite happy and healthy and there are no issues of root rot because the water is constantly moving.
