LG 43LH570V - WebOS version is not specified in the settings

Hello. How to check WebOS version on this model? According to the instructions on this website it’s supposed to be here: https://webostv.developer.lge.com/faq/2016-10-25-general-how-check-platform-version-my-tv
But there is nothing except of software version - 05.00.01. I believe it’s something different?

The LH57 is a lightweight LG Smart TV model based on NetCast, not webOS. For more information, please refer to Smart TV (LH57) vs. NetCast. Thank you.
