Update to the story. In case anyone ends up in a similar situation as myself.
I managed to successfully restore all the files using UFS Explorer Standard edition. The app has analysed the disk structure found several BTRFS UUID, reconstructed the needed trees and restored the missing data. Can highly recommend it.

The original partition was daily snapshotted and was mounted using "compress-force=lzo,space_cache=v2" so I guess the recovery using photorec would be troublesome. Is there any chance to recover the data? Any ideas or advices would be highly appreciated. yours, Kos
