A device with the model number SM-G970U has shown up on Geekbench. Despite its decent specs (Android 9.0, 6GB of RAM and the Snapdragon 855 under its own codename msmnile), it has posted a score of less than 2000 in single-core terms. The speculation revolving around this new listing points to an S10 Lite on un-optimized software.
