You didn't show the command that you used, but yes, it looks like they
are. The devices and seg_pe_ranges parameters for lvs show the details
you're after, eg:

# lvs -o lv_name,vg_name,seg_start,seg_size,devices,seg_pe_ranges
  LV     VG   Start SSize  Devices         PE Ranges
  fedora vg0     0   9.75G /dev/dm-0(0)    /dev/dm-0:0-311
  home   vg0     0  44.44G /dev/dm-0(312)  /dev/dm-0:312-1733
  swap   vg0     0   1.50G /dev/dm-0(1734) /dev/dm-0:1734-1781
