As a general rule, it's not safe to burn leaded fuel at all. that's why MSR specified "unleaded". Though in the U. S. it's moot as you'd have to go out of your way to find leaded gasoline. I also view the fuels other than white gas to be a matter of necessity. IOW, no white gas, so I guess we'll use the kerosene that's more readily available. But last time I saw a multi-fuel stove in such a scenario, it involved changing the jet, and the stove didn't seem to burn quite as cleanly. That might have changed in the last 20 years, but I just stick with white gas.

The avgas is leaded and marketing materials “encourage” using it, FWIW. But yes the efficiency and heat output definitely differ based on the fuel used, some will work better than others for a given stove design. You should be able to combust most of the hydrocarbons regardless of fuel source by adjusting the air intake but any non-hydrocarbon additives will produce strange byproducts which will seem like it’s not burning “cleanly”. e.g. SOx, NOx.
