Would like to know if there is any shorter method to get this mapping of combined output (lvpath, /dev/mapper/ and /dev/dm/* ), possibly a single command.
I don't know this command. I don't have any logical volumes so I cannot experiment with the command on my system. But the man page on lvdisplay tells me to use lvs and that command has a -o switch which can be used to select the attributes you are looking for.

Andrew, thank you for the suggestion. I had already explored lvs -o and I did not see any provision to get device mapper path and dm device path as I expected using that
