Aspidistra is a very unpretentious plant. I think you are right. Central heating and hot air could cause dry leaf tips. And also the stress of transferring plants from the street to the house.
I would not delete the entire sheet. The plant maintains an optimal balance between roots and leaves. Therefore, you can simply cut the dry ends of the leaves. But when the plant "wakes up" and gives young green leaves, then the old leaves can be removed. And at the same time add a fertilizer with a predominance of nitrogen. (Can be sold as fertilizer for non-flowering plants).
In the dark corner you can put an artificial plant. I saw such plants in the store that it's hard to guess that they are not real.
Or to invent and create a florarium with illumination.
Something like this.

I have a small florarium from an old aquarium. He is standing in a dark corner. The phytolamp only shines on plants, its light does not get into the eyes.
There are several plants. I love the Maranta tricolor. Every morning Maranta lifts and opens the leaves. In the evening closes. Sometimes Maranta turns leaves in the afternoon. She does it slowly, but it can be seen moving.
