Every price you see is mark-to-market: what the holding would fetch today. That makes every fall look the same on the way down. A temporary decline is a price that later recovers because the business behind it was fine. A permanent capital loss never comes back, because the business itself was damaged: its earnings shrank for good, it borrowed too much, or it was overtaken.
Companies often confirm the damage later with an impairment — writing down the value of assets or acquisitions that won't earn what was expected — and by then the share price has usually fallen already. Nothing on a price chart tells you which kind of fall you're in; the company's results do. The app shows both the same way, as an unrealised loss, until you sell or the price reaches zero, when it counts the remaining cost as a realised loss.
They look identical on the way down. The difference is in the business, not the chart.
