They could just be transparent and know their techy customers are interested in these sorts of things. Possibly, they want to assure customers that their off-brand phone includes such features.
That would also be my reading. I'm the type of nerd who's interested in minute details of his devices. I'm looking for a new phone currently and my spreadsheet includes columns like the UFS version, minimal brightness (as measured by some independent news site), whether it has a barometer, dual-frequency GNSS, etc. It always requires retrieving info via third parties such as https://docs.google.com/spreadsheets/d/1jXtRCoEnnFNWj6_oFlVW... (GPSTest database), https://phyphox.org/sensordb/, the video mode list on gsmarena.com, etc.
I haven't yet found a manufacturer that publishes sufficient detail such that I can fill out all relevant columns from their official spec page. They're never detailed enough so I can only applaud including more details. There will always be fields that aren't relevant to different subgroups of the audience...
