Is there a method for acquisition from the program?

Answer 1

From your "dmesg" output u can read off the VRAM, so for my Tablet:

Answer 2

Is simple just count how many Mb ram that from usable to real capacity of the ram, example for my lenovo a369i has 512 RAM Module, but in setting app only showing 471 Mb usable so the 41Mb left is reserved for the GPU, so the conclusion is my a369i has 41Mb vram

This method is based from shared graphics memory (wiki)
