lsl6-cd is the "gameid" from larry6.yaml. In the case of the VGA version,
Alexandre filled in lsl6-cd when he first added support for this game;
in the case of the SVGA version, I guessed lsl6hires.

Does the SVGA version work when run with the command from the .desktop
file? If it does, them my guess was correct.

Can you find a scummvm command-line option that does work as a replacement
for lsl6-cd? It might help to use

    scummvm -p /usr/share/games/larry6 --detect
    scummvm -p /usr/share/games/larry6-svga --detect

If I understand scummvm correctly, we want the "ID" column. I don't have
any of the LSL games, but for instance, here's what I get for Loom:

$ scummvm -p /usr/share/games/loom-en --detect
ID             Description                                                Full Path
-------------- ---------------------------------------------------------- ---------------------------------------------------------
loom           Loom (VGA/DOS/English)                                     /usr/share/games/loom-en

I think that means we need a different "longname" directive in the YAML
for one or both of them, to add a (VGA) or (SVGA) suffix (see larry1.yaml
for an example of this).
