I used the new Terra wallet import. The price of stLUNA tokens (https://coinmarketcap.com/currencies/staked-luna/) listed in Koinly is identical to the regular LUNA price but this is incorrect. The price of stLUNA should be higher and should increase over time because each unit of stLUNA can be exchanged for an increasing number of LUNA due to auto-compounding of staking returns. Current exchange rate is 1.027413 Luna per 1 stLUNA (see https://terra.lido.fi/unbond).
