What is lost RAM in android dumpsys meminfo?

I’m comparing memory usage reported by dumpsys meminfo and /proc/meminfo on an Android device and trying to reconcile reported data

Total RAM: dumpsys meminfo reports Total RAM as 2,913,996K. /proc/meminfo lists MemTotal as 2,913,996 kB.

Free RAM: dumpsys meminfo breaks Free RAM into components (cached PSS, cached kernel, and free), summing to 47,257K. /proc/meminfo lists MemFree as 39,996 kB, with additional categories like Cached (136,129 kB) and Mapped. How can these values be directly mapped

Lost RAM: dumpsys meminfo reports Lost RAM as 41,292K. /proc/meminfo does not list "Lost RAM" explicitly. How do I map this to the output of /proc/meminfo
