It is a regular use case to take this data and parse it during contract development and debugging. See e.g. this StackExhange question. But still, currently there is no way to extract this data from the Apps UI.
With a simple copy button for data field in contracts.call extrinsic and contracts.ContractEmitted event sections inside Block Details view, users will be able to take that hex encoded data and decode it with cargo-contract utility (see cargo-contract#481)
